whereas if you were writing it in ASM, both results would be

Not necessarily; not all machines have a divide instruction that
produces both quotient and reminader. (Indeed, some don't have a
divide instruction at all - or are those the ones you were thinking
of?)
On those that do have a divide that produces both quo & rem, a good
compiler will notice that you have both a/b and a%b in close proximity
and collapse them. (Not all compilers are "good", of course.)
