I have written the following program according to the attached image. With my testing, I believe the issue with the program is in the subtraction in Step$1.$ Please help me with getting the subtraction to work correctly, as I believe that it is the only thing holding this program back from working correctly.

$.$data

prompt$1$: $.$asciiz "Enter Dividend: $"$

prompt$2$: $.$asciiz $"$

Enter Divisor: $"$

ans$1$: $.$asciiz $"$

Quotient: $"$

ans$2$: $.$asciiz $"$

Remainder: $"$

$.$text

$.$globl main

main:

# print prompt$1$

la $a$0,$ prompt$1$

li $v$0,4$

syscall

# take in dividend

li $v$0,5$

syscall

# place in remainder reg

li $t$0,0$

move, $t$1,$ $v$0$

# print prompt$2$

la $a$0,$ prompt$2$

li $v$0,4$

syscall

# take in divisor

li $v$0,5$

syscall

move $t$2,$ $v$0$

li $t$3,0$

# initialize quotient reg

li $t$4,0$

# initialize loop counter

li $t$5,32$

Step$1$:

addi $t$5,$ $t$5,-1$ # decrement loop counter

#sub $t$0,$ $t$0,$ $t$2$ # subtract remainder by divisor

#sub $t$0,$ $t$0,$ $t$3$

subu $t$7,$ $t$2,$ $t$0$

sltu $t$8,$ $t$2,$ $t$0$

subu $t$0,$ $t$3,$ $t$8$

bltz $t$0,$ Step$2$b

Step$2$a:

sll $t$4,$ $t$4,1$ # shift quotient

ori $t$4,$ $t$4,1$ # set LSB to $1$

j Step$3$

Step$2$b:

add $t$0,$ $t$0,$ $t$2$ # rem $=$ rem $+$ div

sll $t$4,$ $t$4,1$ # shift quotient

Step$3$:

andi $t$6,$ $t$2,1$ # extract LSB of left divisor

sll $t$6,$ $t$6,31$ # shift bit to MSB

srl $t$2,$ $t$2,1$ # shift left divisor left

srl $t$3,$ $t$3,1$ # shift right divisor left

or $t$3,$ $t$3,$ $t$6$ # set MSB of right divisor

bnez $t$5,$ Step$1$

Done:

# print ans$1$

la $a$0,$ ans$1$

li $v$0,4$

syscall

# print quotient

move $a$0,$ $t$4$

li $v$0,1$

syscall

# print ans$2$

la $a$0,$ ans$2$

li $v$0,4$

syscall

# print remainder

move $a$0,$ $t$1$

li $v$0,1$

syscall

li $v$0,10$
