Long Division Concepts and Techniques

What is the first step when dividing 528 by 2?

• Divide 5 by 2

• Divide 2 by 2

• Divide 8 by 2

• Divide 52 by 2

What should you do if the first digit of the number you are dividing is smaller than the divisor?

• Skip that digit

• Group the first two digits together

• Multiply the divisor by 10

• Subtract the divisor from the first digit

If you group more digits of the number you are dividing at a time, what happens to the number of division steps?

• The number of steps stays the same

• The number of steps increases

• The number of steps decreases

• You cannot group more digits

When you group more digits of the number you are dividing, what happens to how hard each division step is?

• Each step becomes easier

• Each step becomes harder

• The difficulty stays the same

• You don't need to do steps anymore

When you have a 2-digit divisor, what is the smallest number of digits you usually need to look at in the number you are dividing for the first step?

• One digit

• Two digits

• Three digits

• Four digits

What is 528 divided by 24?

• 20

• 22

• 24

• 26

When dividing 528 by 88, why can't you divide 88 into the first two digits (52)?

• 52 is an odd number

• 88 is larger than 52

• You need to use a calculator

• The numbers are too big

To estimate how many times 88 goes into 528, what numbers can you round 88 and 528 to?

• 80 and 500

• 90 and 500

• 90 and 530

• 100 and 500

If you divide 528 by 88 and your first guess is 5, you multiply 5 by 88 to get 440. When you subtract 440 from 528, you get 88. What does this remainder tell you about your first guess?

• Your guess was too high

• Your guess was just right

• Your guess was too low

• You made a mistake in subtraction

When doing long division, if the number you are trying to divide into is smaller than the divisor, what should you do?

• Put a zero in the answer and move to the next digit

• Stop the problem

• Use a calculator

• Add more digits to the divisor
