Idk why this video is called abstract math but what this guy just did is a whole subsubject of math that we studied in highschool, we called it division on Z which Z is the set of all whole numbers (positive and negative) and we use the process that this guy did to solve some question of some big numbers raised to some big number's power (the result is too large too calculate) and sometimes equations of them and get their reminders and study how they evolve for all numbers

There's a rule why or does this just happen to be?
should follow from Fermats Litte Theorem
It follows from Euler's Totient Theorem which is an extension of Fermat's Little Theorem to be used when the modular base isn't prime.
@@erichwithanh7815 this is true, thank you. I was already looking for an extension, but forgot the name lol.
