The div and the divu Instructions

With N-digit integer division there are two results, an N-digit quotient and an N-digit remainder. With 32-bit operands there will be (in general) two 32-bit results. MIPS uses the hi and lo registers for the results:

Here are the MIPS instructions for integer divide. The "u" means operands and results are in unsigned binary.

div    s,t        #  lo <— s div t
                  #  hi <— s mod t
                  #  operands are two's complement

divu   s,t        #  lo <— s div t
                  #  hi <— s mod t
                  #  operands are unsigned
