If a black hole has infinite density why doesn't it have infinite gravity?

Question

For one.. I think this belongs in the Space science(or whatever it's called) topic.. But..
A black hole is created by a Super Nova caving in on itself due to it's extreme gravity.. And it's extreme gravity crushes out of existence, laving nothing but a void that draws in everything around it with it's gravity. The more a black hole takes in, the bigger it grows, and the bigger it's density becomes.. And the bigger it becomes, the more it will draw in and get stronger.
So, technically.. I guess.. Black holes DO have infinite gravity, by that logic. As they're always sucking things in and growing stronger.

Infinite density doesn't mean infinite mass either. Mass determines gravitational pull.
