Answer:

mflo $8

The instructions mflo and mfhi are used to get the results of an integer divide.

Example Program

For this example say that we wish to calculate (y + x) / (y - x).

The argument x is in $8; y is in $9. The quotient is to be placed in $10 and the remainder in $11.

Assume two's complement integers. Here is the program. Sadly, it has some holes. Luckly, you can fill them in.

## Register Use:
##  $8   x
##  $9   y
##  $10  x+y ;  quotient
##  $11  y-x ;  remainder

        .text
        .globl  main

main:
              $8,   $0,  8         # put x into $8
        
              $9,   $0, 36         # put y into $9
        
        addu     $10,  $, $   # $10  = (y+x)
        
        subu     $11,  $, $   # $11  = (y-x)
        
        div      $,  $        # hilo = (y+x)/(y-x)
        
             $10                  # $10  = quotient
        
             $11                  # $11  = remainder
