Question
starting from the MIPS code below that preforms multiplication, I am trying to produce a new function that performs an unsigned integer divide in MIPS
starting from the MIPS code below that preforms multiplication, I am trying to produce a new function that performs an unsigned integer divide in MIPS assembly code. The first number entered is assumed to be the dividend (numerator), the second the divisor. It can be assumed that both numbers will fit into 16 or fewer bits and both are positive. can you help implementing

mloop:
andi $t1, $a0, 1 # get least significant bit of multiplier
