How to Divide a Big Number by a Small Number: A Step-by-Step Guide

Dividing a big number by a small number might seem like a daunting task, especially if you’re not familiar with the process. However, with the right approach and a bit of practice, you can easily master this mathematical operation. In this article, we will walk you through a step-by-step guide on how to divide a big number by a small number, ensuring that you understand the process and can apply it to various scenarios.

Step 1: Understand the Concept

Before diving into the actual steps, it’s crucial to understand the concept of division. Division is the mathematical operation that determines how many times one number (the dividend) can be divided by another number (the divisor) without leaving a remainder. In other words, it’s the inverse of multiplication.

Step 2: Write Down the Numbers

Start by writing down the big number as the dividend and the small number as the divisor. Ensure that both numbers are written in the same format, such as decimal or whole numbers, depending on the context.

Step 3: Set Up the Division Problem

To set up the division problem, place the dividend inside the division symbol (÷) and the divisor on the outside. For example, if you want to divide 123456789 by 3, the division problem would look like this: 123456789 ÷ 3.

Step 4: Perform the Division

Now, it’s time to perform the division. Start by dividing the first digit of the dividend by the divisor. If the first digit is smaller than the divisor, bring down the next digit and combine it with the first digit. Continue this process until you have divided all the digits of the dividend.

Step 5: Write Down the Quotient

As you divide each digit, write down the quotient next to the division symbol. For instance, if you divide 1 by 3, the quotient is 0, and you write it down. If you divide 12 by 3, the quotient is 4, and you write it down.

Step 6: Check for Remainder

After dividing all the digits, check if there’s a remainder. If the remainder is non-zero, it means the division is not exact, and you’ll need to express the result as a decimal. To do this, bring down a decimal point in the quotient and continue dividing the remaining digits of the dividend by the divisor.

Step 7: Express the Result as a Decimal (if necessary)

If there’s a remainder, you’ll need to express the result as a decimal. To do this, multiply the remainder by 10 and bring down the next digit of the dividend. Repeat the division process until you have a desired level of accuracy or until the remainder becomes zero.

Conclusion

Dividing a big number by a small number is a straightforward process once you understand the concept and follow the steps outlined in this article. By practicing these steps, you’ll be able to divide large numbers with ease and confidence. Remember that division is the inverse of multiplication, and with a bit of patience, you can tackle any division problem that comes your way.
