We're dividing 312751 by 25 
We're looking to find how many times 25 goes into 312751.

Going ahead to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 25

Step 2:
When dividing 31 by 25, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 25 from 31 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 25

On to step 3:
62 divided by 25 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 50 from 62 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 25

Step 4:
When dividing 127 by 25, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtract 125 from 127 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 25

Step 5:
The number 25 fits into 25 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1251.0
If we take 25 away from 25, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 25

Going ahead to step 6:
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: 12510.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 25 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 12510.0
If we take 0 away from 10, we end up 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.

Going ahead to step 8:
If we divide 100 by 25, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 12510.04
If we subtract 100 from 100, 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.

Going ahead to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12510.04
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.

Advancing to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12510.04
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.

After the division, we end up with 12510.04 and a remainder of 0.0.
