22. Step 1
• Divide 2 into first
number in the dividend.
2 ) 9 4 7
• Think how many 2’s
will fit into 9.

How many 2’s
will go into 9?
• Write that number directly
above the number you
divided into.

26. Step 5 in Long Division
• This is where you decide
whether you repeat the
5 steps of division.
2 ) 9 4 7
• If your divisor can divide into your new number,
14, or if you have numbers in the dividend
that have not been brought down, you repeat
the 5 steps of division.
