If you have a good compiler, you can already get this.  The low-level
divide function for the MetaWare - Am29000 C compiler returns the /
value in the specified register, and returns the % value in the standard
function return-value register.  Therefore, in code like

	while (n > 0) {
		buf[i++] = (n%10) + '0';
		n /= 10;
	}

only one call to the low-level divide routine is made.
