BEFORE WE START

Sometimes when dividing there is something left over. It is called the remainder. Example: There are 7 bones to share with 2 pups. But 7 cannot be divided exactly into 2 groups, so each pup gets 3 bones, but there will be 1 left over.So when you divide 7 by 2 ,reminder is 1.Then we can say 7 is not completely divisible by 2 as it reminds 1.
