Let's divide 25971572 by 13
We're looking to find how many times 13 goes into 25971572.

Going ahead to step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 13

Step 2:
13 can be fit into 25 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 13 from 25 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 13

Step 3:
When dividing 129 by 13, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 117 from 129, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 13

On to step 4:
If we divide 127 by 13, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 199.0
Deduct 117 from 127 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 13

On to step 5:
13 can be fit into 101 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1997.0
Subtracting 91 from 101 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 13

Moving on to step 6:
13 can be fit into 105 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 19978.0
Subtracting 104 from 105 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 13

Moving on to step 7:
13 goes into 17 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 199781.0
Deduct 13 from 17 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 13

On to step 8:
42 divided by 13 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1997813.0
If we take 39 away from 42, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 13, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1997813.2
Subtract 26 from 30 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.

Advancing to step 10:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1997813.23
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
10 divided by 13 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1997813.23
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1997813.2307
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 1997813.23076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
When dividing 120 by 13, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1997813.230769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1997813.2307692
Deduct 26 from 30 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
The number 13 fits into 40 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1997813.23076923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 1997813.23076923 with a balance of 1e-09.
