We look at the division of 15935628 by 25 
We want to divide 15935628 by 25.

Advancing to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 25

Moving on to step 2:
The number 25 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 25

Step 3:
25 goes into 159 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 150 from 159 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 25

Going ahead to step 4:
93 divided by 25 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 63.0
The remainder is 18 after subtracting 75 from 93.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 25

Step 5:
When dividing 185 by 25, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 637.0
If we subtract 175 from 185, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 25

Moving on to step 6:
25 goes into 106 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6374.0
Subtracting 100 from 106 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 25

On to step 7:
25 can be fit into 62 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 63742.0
Subtracting 50 from 62 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 25

Moving on to step 8:
25 can be fit into 128 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 637425.0
Deduct 125 from 128 and we're left 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 9:
When dividing 30 by 25, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 637425.1
If we take 25 away from 30, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
25 goes into 50 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 637425.12
If we subtract 50 from 50, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 637425.12
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 637425.12
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 637425.12 with a balance of 0.0.
