The lesson for Daring Double Division will tell you how to do the different things you will need to know to take the double division tests.

    When you divide by a two digit number, you continue to follow the four steps: divide, multiply, subtract, and bring down.  When you divide by two digit numbers, the “divide”  step takes a little more thought, because we have not memorized the two digit multiplication facts.

Example:  Divide  150 ÷ 12

Solution:
    Begin by breaking the division into a smaller division problem.  Starting from the first digit in 150, we try to find a number that 12 will divide into at least once.  Our first smaller division is 15 ÷ 12.  We see that there is one 12 in 15, so we write “1” above the 5 of 15.  Then we multiply, subtract, and bring down.
    Now we begin a new division.  Our next smaller division is 30 ÷ 12.  If you are not sure of the division answer, you may need to try more than once to find the number of 12s in 30.  We find that there are two 12s in 30.  We write “2” above the 0 of 150 and then multiply and subtract.
    Since there is no digit to bring down, you are finished.  The remainder is 6 (12 r 6).
    To check the answer, multiply 12 ×12, and then add the remainder, which is 6;
  12 × 12 = 144  144 + 6 = 150  (to check)
 

    Now, that you know how to do double division, you can go on and take the Daring Double Division tests.
