Understanding Partial Quotients in Long Division

The video tutorial explains how to use the partial quotients method for long division. It starts by setting up a division problem with a two-digit dividend and a one-digit divisor. The method involves listing multiples of the divisor and using them to find partial quotients. The process is repeated until the remainder is zero. The partial quotients are then summed to find the final quotient. This method offers flexibility in choosing partial quotients based on known multiples of the divisor.

What is the main advantage of using the partial quotients method over traditional long division?

• It requires less writing.

• It allows flexibility in choosing partial quotients.

• It always results in a remainder of zero.

• It is faster for all division problems.

Why is it helpful to list products of the divisor before starting the division?

• To memorize multiplication tables.

• To quickly identify how many times the divisor fits into the dividend.

• To avoid using a calculator.

• To make the division problem look more complex.

In the partial quotients method, what is the first step after setting up the division problem?

• Subtract the divisor from the dividend.

• Multiply the divisor by the largest possible number.

• Draw a vertical line to record partial quotients.

• Divide the dividend by the divisor directly.

How do you determine the first partial quotient in the example given?

• By using the largest product of the divisor that is less than the dividend.

• By guessing a number.

• By dividing the dividend by the divisor.

• By subtracting the divisor from the dividend repeatedly.

What do you do after finding a partial quotient and multiplying it by the divisor?

• Divide it by the divisor again.

• Add it to the dividend.

• Subtract it from the dividend.

• Multiply it by the next partial quotient.

What is the final step in the partial quotients method to find the quotient?

• Add all partial quotients together.

• Divide the sum of partial quotients by the divisor.

• Subtract all partial quotients from the dividend.

• Multiply all partial quotients together.

What does a remainder of zero indicate in the context of the division problem?

• The divisor is not a factor of the dividend.

• The division was performed incorrectly.

• The divisor is a factor of the dividend.

• The dividend is larger than the divisor.

How does the partial quotients method demonstrate flexibility?

• By allowing any number to be used as a partial quotient.

• By using only even numbers as partial quotients.

• By requiring exact multiplication results.

• By allowing different sets of partial quotients to reach the same quotient.

What is the relationship between the quotient and the divisor in the example given?

• The quotient is half of the divisor.

• The quotient is the product of the divisor and the dividend.

• The quotient multiplied by the divisor equals the dividend.

• The quotient is the sum of the divisor and the dividend.

What is the significance of the statement 'Nineteen times four equals seventy-six' in the context of the video?

• It suggests an alternative method.

• It shows an error in the calculation.

• It verifies the correctness of the division.

• It indicates a remainder in the division.
