103155 divided by 25 
We're looking to find how many times 25 goes into 103155.

On to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 25

Step 2:
When dividing 10 by 25, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 25

Step 3:
25 can be fit into 103 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 100 from 103 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 25

Moving on to step 4:
25 can be fit into 31 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 25 from 31 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 25

Advancing to step 5:
25 goes into 65 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 412.0
Subtracting 50 from 65 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 25

Going ahead to step 6:
If we divide 155 by 25, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 4126.0
If we subtract 150 from 155, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 25, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 4126.2
Deduct 50 from 50 and we're left 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 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4126.2
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4126.2
If we subtract 0 from 0, 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.

In conclusion, the division gives 4126.2 with a balance of 0.0.
