Division Problem Breakdown
1. 3507 : 5
Let's begin with our first problem, 3507 divided by 5. This type of division is a perfect place to start when practicing division. The number 3507 is the dividend, and 5 is the divisor. Here's how we solve it:
- Divide 35 by 5: 35 divided by 5 equals 7. Write 7 above the 5 in the dividend (3507).
- Multiply 7 by 5: 7 times 5 equals 35. Write 35 below the 35 in the dividend.
- Subtract: 35 minus 35 equals 0.
- Bring down the next digit: Bring down the 0 from the dividend.
- Divide 0 by 5: 0 divided by 5 equals 0. Write 0 next to the 7 above.
- Multiply 0 by 5: 0 times 5 equals 0. Write 0 below the 0.
- Subtract: 0 minus 0 equals 0.
- Bring down the next digit: Bring down the 7 from the dividend.
- Divide 7 by 5: 7 divided by 5 equals 1 (with a remainder of 2). Write 1 next to the 0 above.
- Multiply 1 by 5: 1 times 5 equals 5. Write 5 below the 7.
- Subtract: 7 minus 5 equals 2. The remainder is 2.
So, 3507 divided by 5 equals 701 with a remainder of 2. We can write this as 701 R 2. Remember, the remainder is what's left over after the division is complete. Mastering the remainder aspect of division is crucial, as it appears frequently in higher-level math. Understanding remainders will help you avoid common pitfalls as you solve more complex problems. When you get a remainder, always make sure it is smaller than the divisor; otherwise, your division is not complete.
2. 80 / 4 : 9
Next up, we have 80 divided by 4, and then the result divided by 9. This is a slightly different format, but it still relies on the same division principles. Let's break it down:
- First, divide 80 by 4: 80 divided by 4 equals 20.
- Now, divide 20 by 9: 20 divided by 9 equals 2 with a remainder of 2.
So, 80/4:9 equals 2 with a remainder of 2, which can be written as 2 R 2. It is essential to complete the first operation before the second one. This is why we do 80 / 4 first. The result of this initial operation is the dividend of the second operation. Always remember to maintain the order of operations. This is especially important when dealing with more complex problems. Taking the time to understand the order of operations will make solving more complex equations a breeze. Remember that when you divide by a larger number, the quotient will always be less than 1. If you struggle with division with remainders, try using the concept of multiplication.
