        Let the 5 friends be A, B, C, D and E.

                      A                  B                   C                   D                   E













        Give one orange to each friend first. We are left with 10 oranges. Now, we distribute one
        more orange to each. We are left with 5 oranges. Now, we distribute one more orange to
        each of them. We are left with no oranges. We can see that each of them gets 3 oranges.

        So, if we distribute 15 oranges equally among 5 friends, each of them gets 3 oranges. We
        can write this as a division fact, as shown below:

        Thus,  Dividend is the number to be divided.                                  15      ÷     5    =     3
                  Divisor is the number by which we divide.
                  Quotient is the answer obtained on division.                     Dividend      Divisor    Quotient


        Division as Repeated Subtraction                                           Fact-o-meter

        Division is also done using the concept of subtraction.                 To show division as repeated
        Let us divide 12 by 2.                                                  subtraction, subtract until we
                                                                                get 0 finally.


        Step 1: Subtract 2 from 12; 12 – 2 = 10                   Step 2: Subtract 2 from 10; 10 – 2 = 8
        Step 3: Subtract 2 from 8; 8 – 2 = 6                      Step 4: Subtract 2 from 6; 6 – 2 = 4

        Step 5: Subtract 2 from 4; 4 – 2 = 2                      Step 6: Subtract 2 from 2; 2 – 2 = 0

        We subtract 2 from 12 six times to get 0.

        Thus, 12 ÷ 2 = 6.


        Division on a Number Line

        We can divide on number line also. To divide 20 by 5 on a number line, start from 20.
        Take jumps of 5 in backward direction, to reach 0. Count the jumps and get the answer.

                                                   20  ÷      5    =    4
