Assembly Language Program to DIVISION two 32-bit / 16 –bit signed numbers 8086(signed)

In assembly language 8086 we use mnemonics in order to perform arithmetic operations like   in DIV/IDIV division.

So, Let's dive deep into what  DIV and IDIV is ...

DIV:- It  divides unsigned/signed double-word(32bit) by unsigned/signed word(16bit) .

IDIV:-  It  divides signed double-word(32bit) by signed word(16bit) . 

Signed 32/16 bit division:-

data segment

no1 dd 02h          

no2 dw 03h

q dw ?

r dw ?

data ends

code segment

start : assume  cs :code,  ds :data

mov ax ,data

mov ds , ax

lea si , no1

mov ax, [ si ]

mov dx,[ si+2 ]

IDIV no2

mov q , ax

mov r , dx

mov ah ,4ch

int 21h

code ends

end start
