Long Division Concepts and Techniques

What is division primarily used for?

• Adding large numbers together

• Splitting a total into even groups

• Subtracting one number from another

• Finding the square root of a number

In long division, what do we do with the dividend and divisor?

• Subtract the divisor from the dividend

• Add them together

• Divide them one digit at a time

• Multiply them

What is the first step in long division?

• Bring down the next number from the dividend

• Divide the first digit of the dividend by the divisor

• Subtract the divisor from the dividend

• Multiply the divisor by the highest number it can go into

What happens if there's a remainder in a division step?

• The process stops

• It's added to the next digit of the dividend

• It's ignored

• It's multiplied by the divisor

How do we handle remainders in long division?

• Add them to the next step's dividend

• Ignore them completely

• Multiply them by the divisor

• Place them above the division bar

What is 'side math' used for in division?

• To add more steps to the process

• To subtract the remainder

• To simplify the division process

• To handle numbers not in our times table

What do we do if the divisor doesn't fit into the current number?

• Skip to the next number

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

• Stop the division process

• Multiply the divisor by two

What is the purpose of 'guess and check' in side math?

• To double-check the division

• To simplify the dividend

• To estimate the quotient

• To find the exact divisor

When using side math, what should you do if your first guess is too high?

• Try a lower number

• Restart the division process

• Multiply by a higher number

• Add the guess to the dividend

How do we know we're done with the division process?

• When we reach a remainder of zero

• When there are no more digits to bring down

• When we've used all the divisors

• When the dividend is less than the divisor
