It takes a very long time. The oldest fossils are about 3.5 billion years old, but many are not nearly that old. The youngest are probably only about 23 million years old or even less.

So how long does it take for something to fossilize?
"Just because something is 'fossilized' does not mean that it is millions (or even thousands) of years old. When the conditions and materials are right, a bone can become filled with minerals fairly quickly ... Researchers have found that chicken bones and wood can be replaced with minerals in just five to ten years"

its not a fossil until it has turned into rock. It takes centuries for a bone or piece of wood to fossilize, unless there is a constant drip of calcified water, then at least 50 years

A fossil IS rock! Millions of years, the oldest human remains are not fossils, they're still bone.
