We divide 25630028 by 815
We're looking to find how many times 815 goes into 25630028.

On to step 1:
If we divide 2 by 815, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 815

Going ahead to step 2:
The number 815 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 815

Step 3:
256 divided by 815 is 0 with a remainder of 256.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 256 and we're left with 256.
Bring next digit (3) of the dividend behind the 256 and repeat the process: 2563 / 815

Moving on to step 4:
815 goes into 2563 3 times with a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2445 from 2563, we get 118.
Include the next digit (0) from the dividend after 118, then repeat: 1180 / 815

Let's proceed to step 5:
815 goes into 1180 1 times with a remainder of 365.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 815 from 1180, we get 365.
Grab the next digit (0) from the dividend, add it to 365, then carry on: 3650 / 815

Step 6:
The number 815 fits into 3650 4 times, leaving a remainder of 390.
Use 4 as the next digit of our solution. 
Result so far: 314.0
If we subtract 3260 from 3650, we get 390.
Bring next digit (2) of the dividend behind the 390 and repeat the process: 3902 / 815

Let's proceed to step 7:
3902 divided by 815 is 4 with a remainder of 642.
The next digit of our result is 4. 
Result so far: 3144.0
If we subtract 3260 from 3902, we get 642.
Append the next digit (8) from the dividend to 642 and continue with: 6428 / 815

Moving on to step 8:
The number 815 fits into 6428 7 times, leaving a remainder of 723.
The next digit of our result is 7. 
Result so far: 31447.0
Subtract 5705 from 6428 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 9:
The number 815 fits into 7230 8 times, leaving a remainder of 710.
Use 8 as the next digit of our solution. 
Result so far: 31447.8
Subtract 6520 from 7230 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 10:
If we divide 7100 by 815, we get 8 and a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 31447.88
Subtracting 6520 from 7100 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 31447.88 with a remainder of 0.58.
