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:- 12347528
let the number is as written above
its digit sum = 32 = 5
so reminder will be 2 when we divide 5 by 3 we get reminder as 2 so answer will be 2
digit sum of the number is 64 = 10 = 1
reminder is 1
Example :- 50329845467
then digit sum = 53 = 8
when we divide 8 by 3 we get reminder as 2 so answer will be 2
