I just need an accurate total. Yes I know what I am asking is a ridiculous question, but I need it answered for some extra credit and I'm sure as hell not going to go through 9,152,052 digits. I'm hoping by some off chance that perhaps some insane individual actually knows this answer.

That is an accurate answer, there are zero zeros in base 2 in the largest prime.

0, 0's in base 2!!!

Incorrect. Once you get past the base that is the number itself, you will run out of 0's. Right, Bob?
