div $t0,$s1,$s2

Translates into:

div $s1, $s2 mflo $t0

The SPIM extended assembler includes these instructions:

div d,s,t # divide $s by $t. Put the # quotient in $d. Operands are # two's complement. # (pseudoinstruction)

and

divu d,s,t # divide $s by $t. Put the # quotient in $d. Operands are # unsigned. # (pseudoinstruction)

Is the __remainder__ of an integer division
sometimes useful?
