We're dividing 307271 by 25 
We want to divide 307271 by 25.

Let's proceed to step 1:
25 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 25

On to step 2:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 25 from 30, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 25

On to step 3:
25 can be fit into 57 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 50 from 57 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 25

Moving on to step 4:
72 divided by 25 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 50 away from 72, we end up with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 25

On to step 5:
25 can be fit into 227 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1229.0
If we subtract 225 from 227, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 25

Going ahead to step 6:
21 divided by 25 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 12290.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
25 goes into 210 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 12290.8
Deduct 200 from 210 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.

On to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 12290.84
Deduct 100 from 100 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.

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: 12290.84
If we take 0 away from 0, we end up 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.

Step 10:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12290.84
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.

The final result is 12290.84 with a remainder of 0.0.
