Understanding Long Division Concepts

This video tutorial teaches long division with two-digit divisors. It begins with an introduction and a recommendation to watch a previous video on single-digit divisors for better understanding. The tutorial provides two detailed examples: dividing by 16 and dividing by 23. Each example is broken down into steps, including division, multiplication, subtraction, and handling remainders. The video concludes with encouragement to practice the steps at home.

What should you do if you're not familiar with long division with one-digit divisors?

• Continue with the current video.

• Watch the previous video on one-digit divisors.

• Skip to the examples.

• Start with multiplication facts.

In the first step of long division, what are you trying to determine?

• The multiplication result of the divisor.

• The remainder of the division.

• How many times the divisor fits into the first digit of the dividend.

• The subtraction result of the division.

What is the next step after determining how many times the divisor fits into the dividend?

• Bring down the next number.

• Subtract the result from the dividend.

• Multiply the divisor by the quotient.

• Add the numbers.

What should you do if there is a remainder after subtraction?

• Stop the division process.

• Repeat the division process with the new number.

• Multiply the remainder by the divisor.

• Add the remainder to the quotient.

When estimating how many times 16 fits into a number, what should you do if you're unsure?

• Divide the number by 16 directly.

• Multiply 16 by different numbers to find the closest fit.

• Use a calculator.

• Guess and check.

What is the result when 16 divides evenly into a number?

• A remainder of 16.

• A remainder of 0.

• A remainder of 2.

• A remainder of 1.

What is the first step when starting a new division problem with a larger divisor?

• Check if the divisor fits into the first digit of the dividend.

• Estimate the quotient.

• Subtract the divisor from the dividend.

• Multiply the divisor by 10.

How can you handle division with a divisor like 23 if you're not familiar with multiplication facts?

• Divide by a smaller number first.

• Skip the problem.

• Estimate using known multiplication facts.

• Use a calculator.

What should you do if the divisor does not fit into the current number?

• Repeat the division process with the next number.

• Multiply the divisor by a larger number.

• Subtract the divisor from the current number.

• Add more numbers to the dividend.

When estimating how many times 23 fits into 142, what is a helpful strategy?

• Use a calculator.

• Compare 23 to a nearby number like 25.

• Divide 142 by 23 directly.

• Multiply 23 by 10.
