The only thing I see (without testing it) is that you zero dx at the

different in "protected mode" - I assume you mean v86 mode - and real
mode? That's what first comes to mind... try moving it and see if it helps.
By *end* of your loop do you mean:
mov byte ptr ds:[si], dl
mov dx, 0
At the *first* iteration the dl holds the remainders. If that was
removed the divide operation will be dx:ax/bx again, I believe that's
the cause of "Divide Overflow"
If that's what you mean. But I really curious what make the program
"Divide Overflow" again?
By rmode I mean the real DOS, and by pmode I mean WinXP

What's the advantage of moving ax to cx and then testing cx for zero,
compared to just testing ax for zero?
" jcxz ok" was also a guard against the last bit of a digit, I wish I
could compare ax against zero but I haven't learn it yet.

Well, you're closing in on it. As Betov says - one time I do agree with
him - "Courage!"
Well, Thanks a lot, encouragement is really what I needed.
