They don't go anywhere. They get torn apart as the gravitational force of the black hole sucks them in. By the time they are "devoured" as they say in more colourful terminology, they have been reduced to their most elemental particles, and are not a star any more.
The word "devoured", used often in popular press, makes it sound as though a black hole has an intention. It doesn't. That is just how it is pictured, due to the fact that its enormous gravitational pull makes it impossible to 'get away' from it.
The entire process is extremely complex, and would take way too long to explain here. Just type the word 'black hole' into your search engine, and you will have more info. than you know what to do with.
It is a fascinating subject, and worth actually finding out about, rather than listening to the simplistic definitions of them that some people take as being scientific fact.

They don't go anywhere except into the black hole and hit the singularity. They will, however, evaporate out, but not as a star, via Hawking radiation; where a pair of matter and anti-matter particles form with the event horizon between them and the one of the outside escapes the gravity of the black hole. Other than this, our current physical theories cannot explain what happens within a black hole.

--This explanation may explain your question to a degree:
*** g98 7/22 pp. 16-17 Have Scientists Really Found Black Holes? ***
---What Would Make a Black Hole?
PRESENT scientific understanding is that stars shine because of a ceaseless struggle between gravity and nuclear forces. Without gravity to squeeze the gas deep inside the star, nuclear fusion could not take place. On the other hand, without nuclear fusion to resist the pull of gravity, some very strange things can happen to stars.
Scientists believe that when stars about the size of our sun exhaust their nuclear fuel of hydrogen and helium, gravity squeezes them down to hot cinders about the size of the earth, called white dwarfs. A white dwarf may contain as much mass as the sun, but its mass is crammed into a space a million times smaller.
You can think of ordinary matter as mostly empty space, with almost all the mass of each atom located in a tiny nucleus surrounded by a much larger cloud of electrons. But inside a white dwarf, gravity squeezes the electron cloud into a tiny fraction of its previous volume, shrinking the star to the size of a planet. For stars about the size of our sun, at this point there is a standoff between gravity and forces possessed by the electrons, preventing any further compression.
But what of stars heavier than the sun, with more gravity? For stars more than 1.4 times as massive as the sun, the force of gravity is so great that the electron cloud is squeezed out of existence. The protons and electrons then combine into neutrons. The neutrons resist further squeezing, provided the gravity is not too strong. Instead of a white dwarf the size of a planet, the result is a neutron star the size of a small asteroid. Neutron stars consist of the densest known material in the universe.
What, though, if the gravity is further increased? Scientists believe that in stars about three times the mass of the sun, the gravity is too strong for the neutrons to withstand. No form of matter known to physicists can resist the cumulative force of all this gravity. It seems that the asteroid-size ball of neutrons would get squeezed not just into a smaller ball but into nothing, into a point called a singularity, or some other as yet undescribed theoretical entity. The star would apparently disappear, leaving behind only its gravity and a black hole where it used to be. The black hole would form a gravitational shadow in place of the former star. It would be a region in which gravity was so strong that nothing—not even light—could escape.....

^ guy above me, go to wiki, you're dead wrong.
Anyways, in reference to the question, Wikipedia explains what happens quite specifically.
For an uncharged, non-spinning black hole:
"As the object continues to approach the singularity, it will be stretched radially with respect to the black hole and compressed in directions perpendicular to this axis. This phenomenon, called spaghettification, occurs as a result of tidal forces: the parts of the object closer to the singularity feel a stronger pull towards it (causing stretching along the axis), and all parts are pulled in the direction of the singularity, which is only aligned with the object's average motion along the axis of the object (causing compression towards the axis)."
For a spinning black hole:
"While the fate of an observer falling into a non-rotating black hole is spaghettification, the fate of an observer falling into a rotating black hole is much less clear. For instance, in the Kerr geometry, an infalling observer can potentially escape spaghettification by passing through an inner horizon. However, it is unlikely that the actual interior geometry of a rotating black hole is the Kerr geometry due to stability issues, and the ultimate fate of an observer falling into a rotating black hole is currently not known.[21]"
So, that raises the question, what happens if something undergoes spaghettification?
"As objects fall into a black hole, the tidal forces become stronger and stronger until nothing can resist them. The infalling bodies are stretched into thin streams of matter. Eventually, close to the singularity, the forces become large enough to tear molecules apart. For this reason, it would be impossible for a human to survive entering a singularity. The point at which these tidal forces become fatal depends on the size of the black hole. For a very large black hole, such as those found at the center of galaxies, this point will lie well inside the event horizon, so an astronaut may cross the event horizon without noticing any squashing and pulling whatsoever (although it's only a matter of time, because once inside an event horizon, there is no getting out again). For small black holes whose Schwarzschild radius is much closer to the singularity, the tidal effects may become fatal long before the astronaut even reaches the event horizon."'
So now you're probably wondering (among many other things), what happens at the singularity?
"In a non-rotating black hole, the singularity is one-dimensional, extended in the time direction only. In a rotating black hole, the singularity is two-dimensional, extended in time and in longitude."
So now you're either extremely confused, or asking, "will the object ever reach the singularity?":
"Space-time inside the event horizon of an uncharged non-rotating black hole is peculiar in that the singularity is in every observer's future, so all particles within the event horizon move inexorably towards it (Penrose and Hawking)."
So quick summary:
Non-spinning black hole: Star would be pulled in towards the singularity, and would be pulled into thin streams of matter (all molecules would be destroyed). Singularity is one-dimensional (time). The object will continue to move towards the singularity forever.
Spinning: Not enough is known, though it's possible that it'll also be pulled apart into thin streams. Singularity is two-dimensional (time and longitude), most likely ring-shaped. The object will continue to move towards the singularity forever.
It goes against our natural assumptions (as humans) of time and space, but based on the evidence we currently have, that's what most likely happens.
Be sure to check out the Wiki articles on this...

They don't go anywhere. A black hole is something extremely dense in space. Think of space as a big sheet of fabric. When you put something onto it, that thing makes a dent. Think of that dent as gravity. Now, roll a marble towards that dent. If you do it right, the marble will curve towards it and begin falling into the dent, circling around the thing in the center. The marble is now in orbit; the edge of the dent is called the 'event horizon.' Now take something really, really heavy and put it onto your sheet. It will make a really big, really steep dent in the fabric. This is a black hole. Roll your marble towards it, and once the marble reaches the event horizon, it will fall in towards the black hole. The marble doesn't 'go' anywhere, but it is trapped and cannot get out.
I hope this analogy clears things up for you.

Uranus
(IPA: [ jÊËɹeɪ.nÉs, ËjÊ.ɹÉ.nÉs ], named for the Greek word (Îá½ÏανÏÏ), meaning "heaven" or "sky") is the seventh planet from the Sun. It is a gas giant, the third largest by diameter and fourth largest by mass. It is named after Uranus, the Greek god of the sky and progenitor of the other gods. Its symbol is either (astrological) or (astronomical). The first symbol derives from the name of its discoverer, William Herschel. The second symbol is a combination of the devices for the Sun and Mars, as Uranus was the personification of heaven in Greek mythology, dominated by the light of the Sun and the power of Mars. It is also the alchemical symbol of platinum.
Uranus is the first planet discovered in modern times. Sir William Herschel formally discovered the planet on March 13, 1781; the other planets (from Mercury out to Saturn) have been known since ancient times, since they are visible to the naked eye. Uranus' discovery expanded the boundaries of the solar system for the first time in modern human history. It was also the first planet discovered using technology (a telescope) rather than the naked eye.

Well i'm a little rusty on my quantume physics but when anything is sucked into a black hole it is compresed to a singularity. No one knows exactly where they go from there or what ever else happens to them. Sorry. Hope that helps.

They don't get sucked in by something that doesn't exist. Black holes are only an unprovable theory that are perpetrated by 'scientists' that need some vague thing to suck taxpayers money into their pockets. A lot like global warming loonys.

Meteors or stars or anything that falls on a black hole just stays there, just like when meteors fall on Earth, they just stay on the Earth.
