Hi all,
I have this project to code in 8051: "Division of two 16 bit unsigned 
integers being in the internal memory, quotient and remainder should be 
stored".
I find a way to do it but there is a part of the program that i don't 
understand, I attach it.
I've noted which part i don't understand. By "don't understand", means 
that i'm not understanding why do we have to do all those calculations 
to find the quotient and the remainder.

Is there anyone have ideas of it? Or any advice?

Be more precise!
Or do you think we should dig through lots of pages of general 
information to find some part you don't understand?

Which do you mean?

Take a sheet of paper and do this calculation manually, then you see how 
many calculations you must do for a simple division.
