               Sub-topic: Long division

              Introduction - Division means equal distribution. We use long division method for dividing
               large numbers.
              Long Division Method:

        Example 1: 89,892 ÷ 15


                                  5992

                      15      89892

                                75


                                148

                                135

                                  139

                                  135

                                      42


                                       30

                                       12




        Step 1:

              Here, the divisor is a 2-digit number.
              So, consider the number formed by 2 extreme left digits of the dividend.
              It is 89.
              Let us see how many times 15 is contained in 89.
              Now, 15 x 5 = 75 and 15 x 6 = 90.
              75<89 while 90>89.
              So, we will take 75.
              Write 5 in the quotient just above the dividend as shown in the solution.
              Write 75 below 89 and subtract.
              89 – 75 = 14
