        Division as Repeated Subtraction

        I have 25 books. I can keep 5 books in one shelf. So, how many shelves do

        I need in my almirah?


            �    5 books are in the first shelf.
               25 – 5 = 20; 20 books are left.


            �    5 more books are in the second shelf.
               20 – 5 = 15; 15 books are left.


            �    5 more books are in the third shelf.

               15 – 5 = 10; 10 books are left.


            �    5 more books are in the fourth shelf.
               10 – 5 = 5; 5 books are left.


            �    5 more books are in the fifth shelf.

               5 – 5 = 0; No books are left.

        25 books have filled up 5 shelves of almirah.

        We subtracted 5 from 25 repeatedly 5 times. This way of division is called

        repeated subtraction.

        The division fact is           25     ÷    5    =    5


         Use repeated subtraction to divide. One has been done for you.

                                                27 – 9 = 18
                      27 ÷ 9                    18 – 9 =            9 3 times                        3

                                                  9 – 9 =           0
