I know that black holes are formed by dying stars, but what happens to black holes when they evaporate?

Through Hawking radiation, black holes actually do decay, but it takes stupendously long times for even an average black hole to dissipate. That is the reason why astrophysicists calculate that black holes will still exist long after everything else has decayed in the universe hundreds of trillions of years in the future, assuming there isn't a re-collapse of the universe, and assuming that protons do decay after all, as predicted by theory.
Addendum: dimino might be confusing black holes with supermassive stars, which sometimes go supenova. However, the link below is an interesting abstract about "exploding black holes", which are not called supernovas.

Some, maybe all, black holes explode in a phenomenon known as a supernova explosion. From the view point of physics this makes sens and does also provide an answer on the question how the 'heavier' atoms were created. After the Big Bang, only Helium and Hydrogen existed. Supernova explosions provided the answer where the energy came from needed to build the heavier atoms.

According to Hawking radiation, they will eventually "evaporate", but this process would be so slow for a stellar sized or larger black hole that it would take hundreds of trillions of years to occur, so in a sense, the type of black hole one would encounter most, the stellar corpse type, never die.

black holes dont die actually a black hole is a dead sun. nebula-protostar-redgiant-neutronstar is like a supernova then a black hole our sun is a middle age sun it will die in about 5 billion years end will go supernova it will destroy mercury,venus and earth and human will be no more. scientist are still loooking for
goldilocks planet which means a perfect planet. so black hole dont die it is already dead

No. they do not even come to life!
