How to Do Long Division: A Simple Guide for 10-Year-Olds

Long Division Made Easy!

Hi Vienna! Let's learn how to do long division step-by-step. Long division can seem tricky at first, but with a little practice, it becomes easier. Here’s how you can do it:

Step 1: Set Up the Problem

First, you start with a division problem. For example, let’s divide 154 by 7. Write it like this:

    ____
7 | 154

Step 2: Divide

Now, we need to see how many times 7 can fit into the first number of 154. That’s 1. Since 7 can’t fit into 1, we check the next number, 15.

Ask yourself, how many times can 7 go into 15? The answer is 2 times, because 2 x 7 = 14.

Step 3: Write It Down

Write the 2 above the line:

    2
    ____
7 | 154

Step 4: Multiply

Now, multiply the 2 by 7, which gives us 14. Write 14 under 15:

    2
    ____
7 | 154
    -14

Step 5: Subtract

Next, subtract 14 from 15. What do you get?

    2
    ____
7 | 154
    -14
    ----
     1

Step 6: Bring Down the Next Number

Now, bring down the next number (which is 4 from 154) next to 1, making it 14:

    2
    ____
7 | 154
    -14
    ----
     14

Step 7: Repeat the Process

Now, how many times does 7 go into 14? The answer is 2 times (because 2 x 7 = 14). Write the 2 above the line next to the first 2.

    22
    ____
7 | 154
    -14
    ----
     14
     -14

Step 8: Final Subtraction

Now, subtract 14 from 14. What do you get? That’s right, it’s 0!

    22
    ____
7 | 154
    -14
    ----
     14
     -14
     ----
      0

Step 9: Conclusion

Great job! Your answer is 22. So, 154 ÷ 7 = 22.

If you practice this a few times, you will become a long division champ! Remember, it’s all about taking it one step at a time. Happy dividing!
