Q & A

How do you divide 204 by 6?

To divide 204 by 6, start by dividing 20 by 6, which gives 3 (because 6 x 3 = 18). Subtract 18 from 20 to get a remainder of 2. Then, bring down the 4 to make 24, and divide 24 by 6, which gives 4 (because 6 x 4 = 24). The final result is 204 ÷ 6 = 34.

What is the remainder when 204 is divided by 6?

The remainder when 204 is divided by 6 is 0, as 204 can be perfectly divided by 6 with no leftover value.

How do you solve 763 ÷ 7?

To solve 763 ÷ 7, divide 7 by 7 first, which gives 1. Subtract 7 from 7 to get a remainder of 0. Then, bring down the 6 to make 63, and divide 63 by 7, which gives 9. The final result is 763 ÷ 7 = 109.

Why is 9 the quotient when 57 is divided by 8?

When dividing 57 by 8, the closest multiple of 8 is 56 (because 8 x 7 = 56). Since 57 - 56 equals 1, we continue by bringing down the next number. The quotient when dividing 57 by 8 is 7.

How do you handle remainders when dividing numbers?

When dividing numbers and a remainder is left, you write down the quotient, and then you can either express the remainder as part of the final answer or continue by bringing down the next digit to form a larger number to divide.

What is the result when 576 is divided by 8?

To divide 576 by 8, first divide 57 by 8, which gives 7 (since 8 x 7 = 56). Subtract 56 from 57 to get a remainder of 1. Then, bring down the 6 to make 16, and divide 16 by 8 to get 2. The result is 576 ÷ 8 = 72.

What happens when 475 is divided by 5?

To divide 475 by 5, first divide 47 by 5, which gives 9 (because 5 x 9 = 45). Subtract 45 from 47 to get a remainder of 2. Then, bring down the 5 to make 25, and divide 25 by 5 to get 5. The final result is 475 ÷ 5 = 95.

Why is the result of 822 ÷ 3 equal to 274?

To divide 822 by 3, first divide 8 by 3, which gives 2 (since 3 x 2 = 6). Subtract 6 from 8 to get a remainder of 2. Then, bring down the 2 to make 22, and divide 22 by 3 to get 7 (since 3 x 7 = 21). Subtract 21 from 22 to get a remainder of 1, and bring down the last 2 to make 12. Finally, divide 12 by 3 to get 4. The result is 822 ÷ 3 = 274.

What is the significance of multiplying to check division results?

Multiplying the quotient by the divisor verifies the division result. If the product matches the dividend, the division is correct, ensuring no calculation errors.

Why do we write the remainder when dividing if it's not zero?

When dividing numbers and the remainder isn't zero, we either express it as part of the answer (for example, as a fraction or decimal) or indicate it by adding it to the quotient, showing that the division wasn't exact.
