We're dividing 315331 by 12 
Our goal is to divide 315331 by 12.

Let's proceed to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Let's proceed to step 2:
The number 12 fits into 31 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 24 from 31 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 12

Advancing to step 3:
12 goes into 75 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 72 from 75 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

On to step 4:
12 goes into 33 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
Subtract 24 from 33 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 12

Let's proceed to step 5:
When dividing 93 by 12, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 2627.0
Subtract 84 from 93 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

On to step 6:
91 divided by 12 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 26277.0
Deduct 84 from 91 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 26277.5
The remainder is 10 after subtracting 60 from 70.
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:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 26277.58
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 26277.583
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 26277.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 26277.5833 with a remaining 4e-05.
