EAX = 0x30323232

ECX = 0x000000F9

div ecx

EAX = 0x00318D0D

EDX = 0x0000008D

I can't understand why the remainder EDX is 8D. I hope someone can help me with that, Thanks.

Because the remainder equals what's left over after the division, i.e. the difference between the dividend and the product of the divisor and the quotient.

You divided by `0x30323232`

by `0xF9`

and got a quotient of `0x00318D0D`

. If you multiply `0x00318D0D`

by `0xF9`

you get `0x303231A5`

, and therefore the remainder will be `0x30323232 - 0x303231A5`

which equals `0x8D`

.
