        MOV AH, 09H
        LEA DX, MSG
        INT 21H

        MOV AX, 1234  ;Number to be displayed
        CALL display            ;Calls procedure display to display number

        MOV AH, 4CH
        INT 21H

display         proc                ;Procedure TO DISPLAY AVERAGE
            MOV BX, 10          ;Initializes divisor
            MOV DX, 0000H           ;Clears DX

.Dloop1:        MOV DX, 0000H           ;Clears DX during jump
            div BX              ;Divides AX by BX
            PUSH DX             ;Pushes DX(remainder) to stack
            INC CX              ;Increments counter to track the number of digits
            CMP AX, 0           ;Checks if there is still something in AX to divide
            JNE .Dloop1         ;Jumps if AX is not zero

.Dloop2:        POP DX              ;Pops from stack to DX
            ADD DX, 30H         ;Converts to it's ASCII equivalent

;The multiple digit number is: 1234
