I try to find or learn what a division algorithm use NTL(Number Theory Library), and complexity of this algorithm. (need algorithms in GF2X module and ZZ) The implementation of these functions is a lot of code that is difficult to understand what is going in the algorithm.
Has anyone uses NTL? Maybe someone knows standart division and remainder algorithms and their comlexity from number theory and can help?
I can copy-paste listing of some functions.
