Let's divide 39739637 by 904
Our goal is to divide 39739637 by 904.

Step 1:
The number 904 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 904

Going ahead to step 2:
904 goes into 39 0 times 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.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 904

On to step 3:
When dividing 397 by 904, we get 0 with a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Include the next digit (3) from the dividend after 397, then repeat: 3973 / 904

Step 4:
The number 904 fits into 3973 4 times, leaving a remainder of 357.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3616 from 3973 leaves us with 357.
Fetch the next digit (9) from the dividend, attach it to 357 and continue: 3579 / 904

Let's proceed to step 5:
3579 divided by 904 is 3 with a remainder of 867.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 867 after subtracting 2712 from 3579.
Fetch the next digit (6) from the dividend, attach it to 867 and continue: 8676 / 904

Advancing to step 6:
The number 904 fits into 8676 9 times, leaving a remainder of 540.
The next digit of our result is 9. 
Result so far: 439.0
Subtracting 8136 from 8676 leaves us with 540.
Include the next digit (3) from the dividend after 540, then repeat: 5403 / 904

On to step 7:
When dividing 5403 by 904, we get 5 with a remainder of 883.
Put 5 as the next digit of the answer. 
Result so far: 4395.0
The remainder is 883 after subtracting 4520 from 5403.
Bring next digit (7) of the dividend behind the 883 and repeat the process: 8837 / 904

On to step 8:
8837 divided by 904 is 9 with a remainder of 701.
Write down 9 as next digit of the result. 
Result so far: 43959.0
If we subtract 8136 from 8837, we get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Moving on to step 9:
7010 divided by 904 is 7 with a remainder of 682.
The number 7 becomes the next digit in our result. 
Result so far: 43959.7
Deduct 6328 from 7010 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Step 10:
If we divide 6820 by 904, we get 7 and a remainder of 492.
Write down 7 as next digit of the result. 
Result so far: 43959.77
If we subtract 6328 from 6820, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The quotient of the division is 43959.77, and the remainder is 0.492.
