Fast math needed

I am programming with prim numbers in VB6.0 and need a much faster and more accurate function to get the rest and quota of A and B.
In StandardML, the words DIV and MOD are exactly the kind of functions I need.
I do not want to use a loop or int(A/B), because the loop is too slow and floating values and not accurate at all for 16-digit numbers.
Is there any math API to use from another language?
