39907983 ÷ 252 
We're looking to find how many times 252 goes into 39907983.

Advancing to step 1:
252 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 252

Going ahead to step 2:
If we divide 39 by 252, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 252

Moving on to step 3:
If we divide 399 by 252, we get 1 and a remainder of 147.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 252 from 399 to get 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 252

Step 4:
If we divide 1470 by 252, we get 5 and a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 1260 from 1470 and we're left with 210.
Grab the next digit (7) from the dividend, add it to 210, then carry on: 2107 / 252

Let's proceed to step 5:
2107 divided by 252 is 8 with a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we subtract 2016 from 2107, we get 91.
Grab the next digit (9) from the dividend, add it to 91, then carry on: 919 / 252

On to step 6:
When dividing 919 by 252, we get 3 with a remainder of 163.
The next digit of our result is 3. 
Result so far: 1583.0
The remainder is 163 after subtracting 756 from 919.
Fetch the next digit (8) from the dividend, attach it to 163 and continue: 1638 / 252

Advancing to step 7:
252 goes into 1638 6 times with a remainder of 126.
The number 6 becomes the next digit in our result. 
Result so far: 15836.0
If we take 1512 away from 1638, we end up with 126.
Bring next digit (3) of the dividend behind the 126 and repeat the process: 1263 / 252

Going ahead to step 8:
252 goes into 1263 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 158365.0
Subtracting 1260 from 1263 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
252 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 158365.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 252, we get 1 and a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 158365.01
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
480 divided by 252 is 1 with a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 158365.011
The remainder is 228 after subtracting 252 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Our division results in 158365.011 with a remaining 0.0228.
