We look at the division of 25117887 by 71 
We're looking to find how many times 71 goes into 25117887.

Advancing to step 1:
71 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 71

Step 2:
25 divided by 71 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 71

On to step 3:
251 divided by 71 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 213 from 251 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 71

Moving on to step 4:
71 can be fit into 381 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 355 from 381, we get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 71

On to step 5:
The number 71 fits into 267 3 times, leaving a remainder of 54.
The next digit of our result is 3. 
Result so far: 353.0
Deduct 213 from 267 and we're left with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 71

On to step 6:
71 can be fit into 548 7 times, resulting in a remainder of 51.
The next digit of our result is 7. 
Result so far: 3537.0
Subtract 497 from 548 to get 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 71

Advancing to step 7:
71 goes into 518 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 35377.0
The remainder is 21 after subtracting 497 from 518.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 71

On to step 8:
If we divide 217 by 71, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 353773.0
Subtract 213 from 217 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 71 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 353773.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
71 can be fit into 400 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 353773.05
If we take 355 away from 400, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
71 can be fit into 450 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 353773.056
If we subtract 426 from 450, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
When dividing 240 by 71, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 353773.0563
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
The number 71 fits into 270 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 353773.05633
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 353773.05633 with a remaining 5.7e-05.
