Let's divide 25472771 by 815
We want to figure out the number of times 25472771 can be divided by 815.

On to step 1:
815 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 815

Moving on to step 2:
The number 815 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 815

Moving on to step 3:
815 can be fit into 254 0 times, resulting in a remainder of 254.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 254 after subtracting 0 from 254.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 815

On to step 4:
When dividing 2547 by 815, we get 3 with a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2445 from 2547, we get 102.
Append the next digit (2) from the dividend to 102 and continue with: 1022 / 815

On to step 5:
815 goes into 1022 1 times with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 815 from 1022, we get 207.
Include the next digit (7) from the dividend after 207, then repeat: 2077 / 815

On to step 6:
The number 815 fits into 2077 2 times, leaving a remainder of 447.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
If we take 1630 away from 2077, we end up with 447.
Append the next digit (7) from the dividend to 447 and continue with: 4477 / 815

Going ahead to step 7:
The number 815 fits into 4477 5 times, leaving a remainder of 402.
The next digit of our result is 5. 
Result so far: 3125.0
The remainder is 402 after subtracting 4075 from 4477.
Fetch the next digit (1) from the dividend, attach it to 402 and continue: 4021 / 815

Moving on to step 8:
815 goes into 4021 4 times with a remainder of 761.
The next digit of our result is 4. 
Result so far: 31254.0
Subtract 3260 from 4021 to get 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Advancing to step 9:
7610 divided by 815 is 9 with a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 31254.9
Subtracting 7335 from 7610 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
2750 divided by 815 is 3 with a remainder of 305.
The next digit of our result is 3. 
Result so far: 31254.93
Deduct 2445 from 2750 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 11:
The number 815 fits into 3050 3 times, leaving a remainder of 605.
Use 3 as the next digit of our solution. 
Result so far: 31254.933
If we take 2445 away from 3050, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

After the division, we end up with 31254.933 and a remainder of 0.0605.
