                   example 1. 16 ÷ 9 = ?                              by another number, it is written as

                   Dividend = 16                                        a is in the tens place, a + b    a b c

                   Digit in the tens place = 1                          is in the ones place
                   Sum of the digits = 1 + 6 = 7                        Remainder = a + b + c
                   So, Quotient = 1, Remainder = 7.                   example 4. 241 ÷ 9 =?
                                                                      Solution.

                   Digit in the tens place = 7                        tens places = 2 + 4 = 6
                   Sum of the digits = 7 + 1 = 8                      Quotient = 26, Remainder = 2 + 4 + 1 = 7
                   So, Quotient = 7, Remainder = 8.
                                                                      example 5. 620 ÷ 9 = ?

                   Dividend = 23                                      Digit in the hundreds place = 6
                   Digit in the tens place = 2                        Sum of the digits in the hundreds and

                   Sum of its digits = 2 + 3 = 5                      tens places = 6 + 2 = 8
                   So, Quotient = 2, Remainder = 5.                   Quotient = 68, Remainder = 6 + 2 + 0 = 8
