Explanation / Answer

I have created and developed the Assembly program which calculates the 32 bit divison operation A / B. I have included the comments for each part of code and attached the final output of it.

Let me explain you in simpler and in step-by-step manner:-

Step-1:

The initial part is to initialize the code by using the include classes which helps to keep and store the data in the structure way.

Example:-

.cseg
.org 0

HighByte struc
LowByte dd ?
WordLow dd ?
HighByte ends

Step-2:

The next step is to set the data attribute into the values of A and B with their desired input values like,

Example:-

.data
A db "0x3412
B db "0x2010

Step-3:

The final step is to start the code with the moving of an variables for assigning the registers to their respective attributes and their specific location.

Example:-

.code
start:

mov eax, 0x3412
mov ecx, 0x3412
div ecx

Assembly Program:-

; Declared the data segment at the starting point

.cseg
.org 0

HighByte struc
LowByte dd ?
WordLow dd ?
HighByte ends

; Uses two variables with A and B

.data
A db "0x3412 = %llu",11, 8, 0
B db "0x2010 * 27020 = %llu",11, 8, 0

.data?
Bytes dq ?
HighByteNumberVal HighByte <>

; The code starts over here with mul operation

.code
start:

mov eax, 0x3412
mov ecx, 0x3412
div ecx
mov dword ptr[Bytes], eax
mov dword ptr[Bytes + 4], edx
invoke crt_printf, offset A, Bytes

mov eax, 0x2010
mov ecx, 520070
div ecx
mov HighByteNumberVal.LowByte, eax
mov HighByteNumberVal.WordLow, edx
invoke crt_printf, offset B, HighByteNumberVal

inkey
invoke ExitProcess, 0
end start
