Understanding Decimal Division

The video tutorial explains how to divide decimals by setting up a long division problem. It emphasizes the importance of adjusting the divisor to remove any decimals by moving the decimal point to the right. The tutorial then guides through the steps of performing long division, including bringing down numbers and calculating remainders, until the division is complete. The key rule highlighted is that the divisor must not have a decimal point.

What is the first step when dividing decimals using long division?

• Move the decimal point in the divisor to the left.

• Place the number to be divided inside the division house.

• Multiply both numbers by 10.

• Place the divisor inside the division house.

Why is it necessary to move the decimal point in the divisor?

• To make the division easier.

• To ensure the divisor is a whole number.

• To simplify the dividend.

• To align the decimal points.

After moving the decimal, what is the next step in the division process?

• Move the decimal point in the dividend.

• Subtract the divisor from the dividend.

• Bring down the next digit.

• Perform the division as usual.

What should you do if there is a remainder after the first division step?

• Move the decimal point again.

• Add a zero to the remainder.

• Stop the division process.

• Bring down the next digit and continue dividing.

What is a crucial rule to remember about the divisor in decimal division?

• It should be a fraction.

• It should be larger than the dividend.

• It must be a decimal number.

• It cannot have a decimal point.
