Hello Everyone!

I Am New In Assembly Language, and during Practice i got one problem in Number Division. i make Program Which Take 4 Digit In Input and store in DW Array . but on Output Time Program Give Me Wrong output .

For Example.

If I Enter 1234 The output of the Program is "4321" But i want "1234" in output Result .

Please See the Code and tell me if any one know about this.
