Answer to Question #286157 in Assembler for ERTYUI

Question

WRITE A ASSEMBLY CODE ON EMU 8086

Arithmetic Operations(Division) Perform following

Arithmetic Operations

·  10/2

· 15/9

· 3844/5

Answer 1

; 8086 DIV Instruction ( Unsigned Operands)

data segment

ends

code segment

start:

; set segment registers:

   mov ax, data

   mov ds, ax

   mov es, ax   

;****************************************

; Byte with Byte Division

;****************************************

; AL stores the quotient and remainder is stored in AH register

   MOV AX, 10      

   MOV BL, 2     

   DIV Bl         ; al = 5, ah = 0

    MOV AX, 15    

    MOV bL, 9    

    DIV Bl        ; al = 1, ah = 6

;****************************************

; Word with Byte        

;****************************************

; AX stores the quotient and remainder is stored in DX register

   MOV AX,3844

   MOV BX,5

   DIV BX            ; ax = 300h, dx = 0004h

   ; wait for any key....   

   mov ah, 1

   int 21h

   mov ax, 4c00h ; exit to operating system.

   int 21h   

ends

end start ; set entry point and stop the assembler.
