#I still don't understand why we use modulo here to extract the last digit.

make a concrete example and ull notice u dont get hands on the last digit with division
u dont want how often sth can divide sth else, u want the remainder after division. and that's modulo
example: 10 / 8 is 1
versus 10 % 8, which is 2
so when u have 123 and u want the 3, what u need to do is to see what remains after u divided 10 out of 123 as much as it fits into it
123 % 10 is 3. bc that's what remains after u divided 123 / 10
in other words, 123 % 10 is the same as (123 - (123 / 10))
Thank you, now I understand, I was so confused.
