Greeting the Audience
Welcome to our comprehensive guide on how to do long division. We know that this topic can be challenging, but with our step-by-step approach, we believe that you will be able to master it in no time.
What is Long Division?
Long division is a mathematical procedure used to solve complex division problems that cannot be solved mentally. It involves dividing a large number into smaller parts until the remainder is zero or a specific number.
Long division is a fundamental math skill that is taught in elementary and middle school. It is essential to learn this skill, as it helps students understand more complex mathematical concepts later on.
How to Do Long Division: Step-by-Step Guide
Step 1: Divide the Dividend by the Divisor
The first step in long division is to divide the dividend by the divisor. The dividend is the number that you want to divide, and the divisor is the number that you are dividing by.
For example, if you want to divide 156 by 6, 156 is the dividend, and 6 is the divisor. You would write this problem as follows:
| 2 | 6 | ||
| 6 | 1 | 5 | 6 |
First, determine how many times the divisor can go into the first digit of the dividend. In this case, 6 can go into 1 zero times. You would then move to the next digit and bring it down, making the new number 15. You would then divide 6 into 15, which goes in twice, making the new number 12. You continue this process until the dividend is zero or less than the divisor.
Step 2: Multiply the Quotient by the Divisor
Once you have determined how many times the divisor goes into the dividend, you need to multiply the quotient by the divisor. The product of the quotient and the divisor should be written below the dividend, aligned with the digits that you used to calculate the quotient.
Step 3: Subtract the Product from the Dividend
The next step is to subtract the product from the dividend. The result of this subtraction should be written below the product and aligned with the dividends’ digits that you used to calculate the quotient. This subtraction should leave you with a remainder.
Step 4: Bring Down the Next Digit
If there are still digits left in the dividend, you need to bring down the next digit and place it next to the remainder. This new number becomes the new dividend, and you repeat the process starting from Step 1.
Step 5: Repeat the Process
The process should be repeated until there are no more digits left in the dividend. The final result should be written as the quotient with the remainder as a fraction.

FAQs
Q1: How do you know when to stop dividing?
A1: You should stop dividing when the remainder is zero, or the next digit in the dividend is zero. At this point, you have divided the entire number and have found the exact quotient and remainder.
Q2: How do I know where to place the new number when bringing down the next digit?
A2: You should place the new digit next to the remainder.
Q3: What do I do if the divisor does not go into the first digit of the dividend?
A3: If the divisor does not go into the first digit, you should try the next digit, making the number larger.
Q4: What if the divisor has a decimal?
A4: If the divisor has a decimal, you should move the decimal point to the right until the divisor is a whole number. You should then move the decimal point in the same direction for the dividend and quotient.
Q5: Can long division be done with any numbers?
A5: Yes, long division can be done with any numbers, as long as you follow the steps outlined in this guide.
Q6: Can long division be used to divide decimals?
A6: Yes, long division can be used to divide decimals. The process is the same as dividing whole numbers, but you need to pay attention to decimal placement.
Q7: How can I check my answer?
A7: You can check your answer by multiplying the quotient by the divisor and adding the remainder. The result should be the original dividend.
