factorial - Finding all the zeroes in $100!$

Is there a way to find all the $0$s in $100!$? (Including zeroes that come between two non-zero numbers)



I know that to find the $0$s at the end we can use the greatest integer method. I was just curious if a method exists to find the remaining zeroes, too. (Of course without finding the actual value of $100!$ and counting, as is done in the only answer to this previous question: How many zeroes are in 100!.)
