Understanding the three-digit number

In the world of numbers, three-digit numbers play an essential role in various mathematical operations. As a result, understanding the structure and breakdown of three-digit numbers can make the division process easier and more efficient. To gain a deeper understanding, let’s take a closer look at how three-digit numbers are formed and the significance of each digit.

Breakdown of three-digit numbers and their structure

A three-digit number consists of hundreds, tens, and ones. Consequently, each digit holds a specific value and place within the number. To elaborate further, here’s a breakdown of the structure and significance of each digit:

Hundreds: The digit in the hundreds place represents the number of hundreds in the given number. It can range from 1 to 9.

Tens: The digit in the tens place represents the number of tens in the given number. It can range from 0 to 9.

Ones: The digit in the one’s place represents the number of ones in the given number. It can range from 0 to 9.

Understanding the breakdown of three-digit numbers allows us to visualize and comprehend their value. Moreover, this knowledge is vital when performing mathematical operations like division. By recognizing the significance of each digit, we can effectively solve division problems involving three-digit numbers with remainders.

Divisor and Quotient

Explanation of the divisor and quotient in division

When performing division, it is important to understand the terms divisor and quotient.

The divisor is the number that you divide by. The number determines how many times the dividend will be divided. For example, in the division problem 789 ÷ 3, the divisor is 3.

The quotient is the result of the division. It is the answer to the division problem. It represents the number of times the divisor can be subtracted from the dividend. Using the same example, the quotient in the division problem 789 ÷ 3 is 263.

Example: Division with Remainders

Sometimes, when performing division, there is a remainder left over. It occurs when the divisor does not divide evenly into the dividend. For example, in the division problem 789 ÷ 3, the quotient is 263 with a remainder of 0. It means that 3 can be subtracted from 789 exactly 263 times.

However, if we divided 796 by 3, the quotient would be 265 with a remainder of 1. It indicates that 3 can be subtracted from 796 exactly 265 times, with 1 left over.

It is important to note the remainder when performing division as it provides additional information about the division problem.

Steps to Perform Three-Digit Division

Following a step-by-step process is essential to ensure accuracy when dividing three-digit numbers. Here are the steps to perform three-digit division with remainders:

  • Set up the division problem: Write the dividend (the number to be divided) inside the division bracket and the divisor (the number you are dividing by) outside the bracket. Place the quotient (the result of division) above the line.
  • Divide the leftmost digit: Divide the leftmost digit of the dividend by the divisor. Write the quotient above the line and the remainder next to the next digit of the dividend.
  • Multiply and subtract: Multiply the quotient obtained in the previous step by the divisor and subtract it from the portion of the dividend you just worked with. Write the result below the line.
  • Bring down the next digit: Bring down the next digit of the dividend and add it to the result obtained in the previous step.
  • Repeat the process: Repeat steps 2 to 4 until you have divided all the digits of the dividend.
  • Write the final remainder: If there is a remainder after dividing all the digits, write it next to the quotient as the final remainder.

To become comfortable with three-digit division, practicing these steps using different three-digit numbers is important. Additionally, remember to double-check your work and ensure the accuracy of your division.
