We look at the division of 39856957 by 904 
We want to divide 39856957 by 904.

Step 1:
When dividing 3 by 904, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 904

Moving on to step 2:
39 divided by 904 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 904

Going ahead to step 3:
904 can be fit into 398 0 times, resulting in a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 398, we end up with 398.
Take the next digit (5) from the dividend and append it to 398, then repeat: 3985 / 904

Going ahead to step 4:
3985 divided by 904 is 4 with a remainder of 369.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3616 from 3985, we get 369.
Include the next digit (6) from the dividend after 369, then repeat: 3696 / 904

Moving on to step 5:
When dividing 3696 by 904, we get 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 44.0
Subtract 3616 from 3696 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 904

Advancing to step 6:
When dividing 809 by 904, we get 0 with a remainder of 809.
Write down 0 as next digit of the result. 
Result so far: 440.0
The remainder is 809 after subtracting 0 from 809.
Include the next digit (5) from the dividend after 809, then repeat: 8095 / 904

Let's proceed to step 7:
When dividing 8095 by 904, we get 8 with a remainder of 863.
Write down 8 as next digit of the result. 
Result so far: 4408.0
Subtract 7232 from 8095 to get 863.
Append the next digit (7) from the dividend to 863 and continue with: 8637 / 904

Going ahead to step 8:
904 goes into 8637 9 times with a remainder of 501.
The next digit of our result is 9. 
Result so far: 44089.0
If we subtract 8136 from 8637, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 9:
When dividing 5010 by 904, we get 5 with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 44089.5
If we take 4520 away from 5010, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
4900 divided by 904 is 5 with a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 44089.55
If we subtract 4520 from 4900, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 44089.55 with a remaining 0.38.
