We look at the division of 12604335 by 308 
Our goal is to divide 12604335 by 308.

Moving on to step 1:
308 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 308

Moving on to step 2:
308 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 308

Going ahead to step 3:
The number 308 fits into 126 0 times, leaving a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 308

Moving on to step 4:
1260 divided by 308 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 28 after subtracting 1232 from 1260.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 308

Going ahead to step 5:
When dividing 284 by 308, we get 0 with a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 284 after subtracting 0 from 284.
Append the next digit (3) from the dividend to 284 and continue with: 2843 / 308

Moving on to step 6:
2843 divided by 308 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 409.0
Subtracting 2772 from 2843 leaves us with 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 308

On to step 7:
308 goes into 713 2 times with a remainder of 97.
The next digit of our result is 2. 
Result so far: 4092.0
Subtracting 616 from 713 leaves us with 97.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 308

Moving on to step 8:
308 goes into 975 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 40923.0
Subtracting 924 from 975 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
510 divided by 308 is 1 with a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 40923.1
The remainder is 202 after subtracting 308 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
308 can be fit into 2020 6 times, resulting in a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 40923.16
Subtract 1848 from 2020 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
308 goes into 1720 5 times with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 40923.165
If we take 1540 away from 1720, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
If we divide 1800 by 308, we get 5 and a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 40923.1655
Deduct 1540 from 1800 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 40923.1655 with a remainder of 0.0026.
