To calculate reminder on dividing the number by 27 and 37
-------------------------------------------------
Let me explain this rule by taking examples consider number 34568276, we have to calculate the reminder on diving this number by 27 and 37 respectively. make triplets as written below starting from units place
34.........568..........276
now sum of all triplets = 34+568+276 = 878 divide it by 27 we get reminder as 14 divide it by 37 we get reminder as 27
-------------------------------------------------
Example. other examples for the clarification of the rule let the number is 2387850765

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
