Dividing in Assembler x86

Question

My college gave me a exercise:

1. Create a new document in Jasmin

2. Use the AL-Register to to add 9 to 8.

3. Subtract 2.

Answer 1

div operation divides (unsigned) the value in the AX, DX:AX, or EDX:EAX registers (dividend) by the source operand (divisor) and stores the result in the AX (AH:AL), DX:AX, or EDX:EAX registers.

source

so, to divide value in al, you need to do:

mov ah, 0 # clean up ah, also you can do it before, like move ax, 9
mov bl, 7 # prepare divisor
div bl # al = ax / bl, ah = ax % bl

after that al will contain quotient and ah will contain remainder
