For large integer numbers, the 'Schoolbook division algorithm' generally has the best performance.
If you Google for it, you will find plenty of references. Here is one:

If you have to tackle very large integer numbers (like for very large prime number testing/generation) you could use the Burnikel & Ziegler 'divise and conquer' method.

I have used GMP in C programs but not in a MASM program. If you convert the headers it should work fine as it is a standard DLL. Also available as a static lib.
