25600856 ÷ 307 
We want to figure out the number of times 25600856 can be divided by 307.

Going ahead to step 1:
If we divide 2 by 307, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 307

Advancing to step 2:
307 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 307

On to step 3:
When dividing 256 by 307, we get 0 with a remainder of 256.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 256 to get 256.
Include the next digit (0) from the dividend after 256, then repeat: 2560 / 307

Let's proceed to step 4:
2560 divided by 307 is 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 2456 from 2560 leaves us with 104.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 307

Moving on to step 5:
307 can be fit into 1040 3 times, resulting in a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 921 from 1040 and we're left with 119.
Take the next digit (8) from the dividend and append it to 119, then repeat: 1198 / 307

Moving on to step 6:
1198 divided by 307 is 3 with a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 833.0
Subtracting 921 from 1198 leaves us with 277.
Include the next digit (5) from the dividend after 277, then repeat: 2775 / 307

Advancing to step 7:
If we divide 2775 by 307, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 8339.0
Subtracting 2763 from 2775 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 307

Step 8:
The number 307 fits into 126 0 times, leaving a remainder of 126.
The next digit of our result is 0. 
Result so far: 83390.0
Subtract 0 from 126 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
307 goes into 1260 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 83390.4
If we take 1228 away from 1260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
307 can be fit into 320 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 83390.41
Subtracting 307 from 320 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
307 goes into 130 0 times with a remainder of 130.
The next digit of our result is 0. 
Result so far: 83390.41
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
307 can be fit into 1300 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 83390.4104
The remainder is 72 after subtracting 1228 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
When dividing 720 by 307, we get 2 with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 83390.41042
Subtracting 614 from 720 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
1060 divided by 307 is 3 with a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 83390.410423
Subtracting 921 from 1060 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 15:
307 can be fit into 1390 4 times, resulting in a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 83390.4104234
If we take 1228 away from 1390, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 16:
307 can be fit into 1620 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 83390.41042345
The remainder is 85 after subtracting 1535 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 83390.41042345 with a remainder of 8.5e-08.
