    friends , today i gonna show you how to divide any 2 digit no by 9 in 5 secs

    Example: 45, 47

    1] 45:
    in 45 4 is the 1st no
    so, we write 4 in the answer first

    then we add the each digit of the number ; in here 4 and 5 ; 4+5=9
    then we divide the sum by 9 ; in here 9 ; 9/9 = 1

    then we add the quotient of the division to the first digit ; in here 4; 4+1 =5


    my answer: 5


    47:

    in 47 , if we follow the same method;

    first - digit - 4

    so , write 4 in answer 1st

    2nd - add the digits in the number; here- 4+7 = 11

    and when we divide 11/9 , it gives 1 as quotient and 2 as remainder

    so , we add 1 to the 1st digit of the no ; in this case - 4 + 1 = 5

    so, my answer will be 5 as quotient , 2 as remainder

    similarly we can divide any 2 digit number by 9 in 5 secs

    Let me try.. My Number is : 85 / 9

    Step 1 : 8+5 =13

    Step 2 : 13/9 = quotient = 1 , remainder = 4

    Step 3 : 8+1 =9


    So the Ans is Quotient = 9 and Remainder = 4
