I thought they are pulling my legs (Eurasia rule ?)

Actually I quite don't understand any of the layouts. I was taught and I always did/do as follows.

Code:

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

So the divisor is on the right not on the left. Of course one can save the writing down of the quotient, writing it in one line. I wrote it in multiple lines to show the progression.

So, like the Mexican layout, if you have difficulty doing the subtractions (to obtain the remainders at each step) in your head, you have to do them "out of shot" on a separate bit of paper? The English long division method does the subtractions "in shot".
