Code:

10020316 | 124
  10       8  (1st operation)
  100      80  (2nd op)
    11     808 (3rd op)
    111    8080 (4th op)
       0   80809 (5th op)

What is above method called ? Is it Argentina way ? Your own style ?

At first I don't understand why the 3 and the 6 were not pulled down.
I now get it. The numbers are the modulus.

1002 % 124 = 10
10020 % 124 = 100
100203 % 124 = 11
...

It almost look as if everything is done in the head. Amazing !

I like this style, but I would probably write the quotient on top, to line up digits.
Modulus is already in staircase form, so relevant quotient digit can be located by looking up.
