You know that 8 x 50 is 400 and 8 x 60 is 480. The quotient will be between 50 and 60.
You can use estimation and place value to help you figure out where to place the first digit.
An estimation, like 600 divided by 6, will show you that the answer should be around 100, not 10 or 1000.
An estimation, like 600 divided by 6, will show you that the answer should be around 100, not 10 or 1000.
Estimating before dividing helps you gauge the size of the quotient, making it easier to determine the first digit. For example, estimating that 624 is close to 600 and 6 is close to 6 suggests that the quotient will be around 100. This initial estimation allows you to quickly identify that the first digit in the quotient should be 1, as 6 goes into 60 ten times, guiding you to a more accurate division process. Overall, it streamlines calculations and reduces the risk of errors.

425 is less than 100*9 = 900 so the first digit of the quotient cannot be in the hundreds (or higher) place. 425 is greater than (or equal to) 10*9 = 90 so the first digit of the quotient cannot be in the units (or lower) place. That only leaves the tens place.
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
