We look at the division of 13105857 by 725 
Let's see how many times 725 fits into 13105857.

Going ahead to step 1:
If we divide 1 by 725, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 725

Let's proceed to step 2:
When dividing 13 by 725, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 725

On to step 3:
If we divide 131 by 725, we get 0 and a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Take the next digit (0) from the dividend and append it to 131, then repeat: 1310 / 725

Going ahead to step 4:
The number 725 fits into 1310 1 times, leaving a remainder of 585.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 725 away from 1310, we end up with 585.
Append the next digit (5) from the dividend to 585 and continue with: 5855 / 725

Going ahead to step 5:
5855 divided by 725 is 8 with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 5800 from 5855 and we're left with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 725

Moving on to step 6:
When dividing 558 by 725, we get 0 with a remainder of 558.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtracting 0 from 558 leaves us with 558.
Grab the next digit (5) from the dividend, add it to 558, then carry on: 5585 / 725

Let's proceed to step 7:
If we divide 5585 by 725, we get 7 and a remainder of 510.
The number 7 becomes the next digit in our result. 
Result so far: 1807.0
If we take 5075 away from 5585, we end up with 510.
Include the next digit (7) from the dividend after 510, then repeat: 5107 / 725

On to step 8:
725 goes into 5107 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 18077.0
The remainder is 32 after subtracting 5075 from 5107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
725 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 18077.0
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 10:
725 can be fit into 3200 4 times, resulting in a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 18077.04
If we subtract 2900 from 3200, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
725 can be fit into 3000 4 times, resulting in a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 18077.044
Subtract 2900 from 3000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 18077.044 and a remainder of 0.01.
