           21 ÷ 7 = 3                                            I'm a number that is always fair.

                                       7 × 3 = 21                I split things equality, with a neat share.

         Write two division facts for each of the following. One has been done

         for you.



          Multiplication Fact                                       Division Facts


                  5 × 8 = 40                    40  ÷  5  =  8                       40  ÷  8  =  5



                  3 × 9 = 27                          ÷          =                         ÷         =



                  8 × 2 = 16                          ÷          =                         ÷         =


        Long Method of Division


        The symbol for long division is



                                                            Quotient
        We write it as follows:                    Divisor    Dividend


        Let us divide 72 by 8.


        Step 1:  Write 72 ÷ 8 as shown.                                                   8 72


        Step 2:   Recall  the  multiplication

                     table  of  8  till  we  get  the
                     number 72. Write 9 in place

                     of quotient.



        Step 3:  8 × 9 = 72. Write 72 below 72                                 Divisor            9      Quotient

                     and subtract to get zero.                                               8 72        Dividend
                                                                                             – 72
                     So, 72 ÷ 8 = 9.                                                             0
