ceil might not be working because the floating-point value is so large that it always represents an integer. (I think the first part of your answer actually relies on this behaviour.)

This might be interesting to you. See libdivide_internal_u32_gen and libdivide_u32_do

The 2**(32+x)s can be replaced with P<<x (in a few places you need brackets though)
