Step 1 in 2 Digit Short Division
• Divide 21 into first number in the dividend.
2 1) 9 4 8
• 21 will not go into 9 so you look at 94.
4
How many 20’s will go into 90?
Dad
1. Divide
• Now divide 20 into 90 & put your answer above the 4.
• Round off 21 and 94 in your head.

Step 5 in 2 Digit Short Division
• This is where you decide whether you repeat the 5 steps of division.
• If your divisor can divide into your new number, 108, or if you have numbers in the dividend that have not been brought down, you repeat the 5 steps of division.
5. Repeat or Remainder
