We look at the division of 25741865 by 518 
We want to divide 25741865 by 518.

Advancing to step 1:
If we divide 2 by 518, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 518

Going ahead to step 2:
518 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 518

Let's proceed to step 3:
The number 518 fits into 257 0 times, leaving a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 257, we end up with 257.
Append the next digit (4) from the dividend to 257 and continue with: 2574 / 518

On to step 4:
2574 divided by 518 is 4 with a remainder of 502.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2072 away from 2574, we end up with 502.
Fetch the next digit (1) from the dividend, attach it to 502 and continue: 5021 / 518

Moving on to step 5:
If we divide 5021 by 518, we get 9 and a remainder of 359.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 4662 from 5021, we get 359.
Append the next digit (8) from the dividend to 359 and continue with: 3598 / 518

Going ahead to step 6:
3598 divided by 518 is 6 with a remainder of 490.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
The remainder is 490 after subtracting 3108 from 3598.
Grab the next digit (6) from the dividend, add it to 490, then carry on: 4906 / 518

Moving on to step 7:
When dividing 4906 by 518, we get 9 with a remainder of 244.
Put 9 as the next digit of the answer. 
Result so far: 4969.0
If we take 4662 away from 4906, we end up with 244.
Fetch the next digit (5) from the dividend, attach it to 244 and continue: 2445 / 518

Advancing to step 8:
518 goes into 2445 4 times with a remainder of 373.
Use 4 as the next digit of our solution. 
Result so far: 49694.0
Subtracting 2072 from 2445 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
518 goes into 3730 7 times with a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 49694.7
Deduct 3626 from 3730 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
If we divide 1040 by 518, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 49694.72
If we subtract 1036 from 1040, we 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 11:
518 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 49694.72
If we take 0 away from 40, we end up 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.

On to step 12:
When dividing 400 by 518, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 49694.72
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 49694.72 with a remainder of 0.004.
