To calculate reminder on dividing the number by 3

Method:- first calculate the digit sum , then divide it by 3, the reminder in this case will be the required reminder

example:- 1342568
let the number is as written above
its digit sum = 29 = 11 = 2
so reminder will be 2

Example.

Take some others
34259677858
digit sum of the number is 64 = 10 = 1
reminder is 1

similarly let the number is 54670329845
then digit sum = 53 = 8
when we divide 8 by 3 we get reminder as 2 so answer will be 2
