We divide 30686980 by 904
We're looking to find how many times 904 goes into 30686980.

Going ahead to step 1:
904 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 904

On to step 2:
When dividing 30 by 904, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 904

Let's proceed to step 3:
904 can be fit into 306 0 times, resulting in a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Fetch the next digit (8) from the dividend, attach it to 306 and continue: 3068 / 904

Moving on to step 4:
The number 904 fits into 3068 3 times, leaving a remainder of 356.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2712 from 3068 and we're left with 356.
Take the next digit (6) from the dividend and append it to 356, then repeat: 3566 / 904

On to step 5:
The number 904 fits into 3566 3 times, leaving a remainder of 854.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 2712 from 3566 leaves us with 854.
Take the next digit (9) from the dividend and append it to 854, then repeat: 8549 / 904

Let's proceed to step 6:
8549 divided by 904 is 9 with a remainder of 413.
Write down 9 as next digit of the result. 
Result so far: 339.0
Subtract 8136 from 8549 to get 413.
Take the next digit (8) from the dividend and append it to 413, then repeat: 4138 / 904

Going ahead to step 7:
904 can be fit into 4138 4 times, resulting in a remainder of 522.
Use 4 as the next digit of our solution. 
Result so far: 3394.0
Deduct 3616 from 4138 and we're left with 522.
Append the next digit (0) from the dividend to 522 and continue with: 5220 / 904

On to step 8:
904 goes into 5220 5 times with a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 33945.0
If we subtract 4520 from 5220, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 9:
904 can be fit into 7000 7 times, resulting in a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 33945.7
Subtract 6328 from 7000 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 10:
When dividing 6720 by 904, we get 7 with a remainder of 392.
The number 7 becomes the next digit in our result. 
Result so far: 33945.77
Subtracting 6328 from 6720 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Our division results in 33945.77 with a remaining 0.392.
