I expect the quotient, remainder, and modulo procedures of R5RS to be provided by an R5RS-backward-compatibility library of some sort. The same compiler techniques that would be used to compile fixnum+ into a single instruction would be used to compile quotient into a single instruction on architectures that make that possible. Will
