We look at the division of 25940665 by 571 
We're looking to find how many times 571 goes into 25940665.

Moving on to step 1:
571 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 571

Going ahead to step 2:
571 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 571

On to step 3:
571 goes into 259 0 times with a remainder of 259.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 259 after subtracting 0 from 259.
Grab the next digit (4) from the dividend, add it to 259, then carry on: 2594 / 571

Advancing to step 4:
571 goes into 2594 4 times with a remainder of 310.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2284 from 2594, we get 310.
Include the next digit (0) from the dividend after 310, then repeat: 3100 / 571

Moving on to step 5:
If we divide 3100 by 571, we get 5 and a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 2855 from 3100 leaves us with 245.
Bring next digit (6) of the dividend behind the 245 and repeat the process: 2456 / 571

Going ahead to step 6:
571 can be fit into 2456 4 times, resulting in a remainder of 172.
The next digit of our result is 4. 
Result so far: 454.0
If we take 2284 away from 2456, we end up with 172.
Include the next digit (6) from the dividend after 172, then repeat: 1726 / 571

Advancing to step 7:
The number 571 fits into 1726 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 4543.0
If we take 1713 away from 1726, we end up with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 571

Going ahead to step 8:
The number 571 fits into 135 0 times, leaving a remainder of 135.
Put 0 as the next digit of the answer. 
Result so far: 45430.0
Deduct 0 from 135 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
571 can be fit into 1350 2 times, resulting in a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 45430.2
If we take 1142 away from 1350, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
The number 571 fits into 2080 3 times, leaving a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 45430.23
Subtracting 1713 from 2080 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 11:
The number 571 fits into 3670 6 times, leaving a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 45430.236
Deduct 3426 from 3670 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 12:
If we divide 2440 by 571, we get 4 and a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 45430.2364
Deduct 2284 from 2440 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 13:
The number 571 fits into 1560 2 times, leaving a remainder of 418.
The next digit of our result is 2. 
Result so far: 45430.23642
If we subtract 1142 from 1560, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 14:
If we divide 4180 by 571, we get 7 and a remainder of 183.
The next digit of our result is 7. 
Result so far: 45430.236427
If we take 3997 away from 4180, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 15:
If we divide 1830 by 571, we get 3 and a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 45430.2364273
If we take 1713 away from 1830, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 16:
1170 divided by 571 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 45430.23642732
Subtract 1142 from 1170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 45430.23642732 and a remainder of 2.8e-08.
