You are requesting a 32/32 divide into 47 bit result. I would question whether you actually need that accuracy. Virtually all real time 3D on microcomputers use 16 bit (or less) projection accuracy. So I suggest you keep the values you wish to project within 16 bits. So your divide will look like (x<<15)/y. If you want a 32 bit world space, then you can do simple maths to still keep projections within the 16bit range.
