I'm a taker if you have some algorithm to reuse 32-bit divide
in wideint division instead of scanning bits :)
I remember the divide was giving me some trouble. The idea was
to try and use the built in registers and limits of the assembly
to take advantage of full 128bit division, unfortunately if the
result is too large to fit in a 64bit result it breaks, rather
than giving me half the result and letting me work with it.
Still I think I'll impliment my own version and then if it's
faster I'll submit it.
