We divide 312106 by 12
Our goal is to divide 312106 by 12.

Step 1:
12 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 12

Moving on to step 2:
If we divide 31 by 12, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 24 from 31 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 12

Going ahead to step 3:
72 divided by 12 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 72 from 72, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

Going ahead to step 4:
1 divided by 12 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 260.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

Going ahead to step 5:
12 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 2600.0
If we take 0 away from 10, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

On to step 6:
106 divided by 12 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 26008.0
Deduct 96 from 106 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.

Step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 26008.8
Subtracting 96 from 100 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.

Moving on to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 26008.83
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 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 26008.833
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.

The final outcome is 26008.833, with a leftover of 0.0004.
