It does not have to be. 864/2 = 432. The first digit of the quotient is not in the tens place.
If you mean 18.88 divided by 4 then the quotient is 4.72 and the first digit of 4 is in the ones or units place
You can use estimation and place value to help you figure out where to place the first digit.
You look at the place value.
In the highest place value.
Yes, that's true.
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.
The tenth place because the quotient is .682 and the six is in the tens place which represents 6/10.
41)3972...since 41>39 you won't have the first digit of the quotient in the hundreds place. it will be in the tens place instead. if the first two digits were 41 or greater then you would. hope that helps.
To look at the numbers in the division problem
by rounding 624 down to 600, you know that 600 divided by 6 is 100, so the first digit will probably be a 1
You know that 8 x 50 is 400 and 8 x 60 is 480. The quotient will be between 50 and 60.
