We're dividing 312281 by 25 
We want to figure out the number of times 312281 can be divided by 25.

Going ahead to step 1:
3 divided by 25 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 25

Step 2:
31 divided by 25 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 25 from 31, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 25

Advancing to step 3:
62 divided by 25 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 50 away from 62, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 25

On to step 4:
When dividing 122 by 25, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we subtract 100 from 122, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 25

On to step 5:
When dividing 228 by 25, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1249.0
Deduct 225 from 228 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 25

Step 6:
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: 12491.0
Subtracting 25 from 31 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 25 fits into 60 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 12491.2
The remainder is 10 after subtracting 50 from 60.
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:
25 can be fit into 100 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12491.24
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12491.24
Subtract 0 from 0 to 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.

Advancing to step 10:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12491.24
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.

In conclusion, the division gives 12491.24 with a balance of 0.0.
