We look at the division of 156071 by 12 
Let's see how many times 12 fits into 156071.

On to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Let's proceed to step 2:
If we divide 15 by 12, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 12 from 15 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 12

Going ahead to step 3:
The number 12 fits into 36 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 12

Moving on to step 4:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 130.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 12

On to step 5:
If we divide 7 by 12, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 1300.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

On to step 6:
12 can be fit into 71 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 13005.0
Subtract 60 from 71 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 12, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 13005.9
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 13005.91
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 13005.916
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13005.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 13005.9166, with a leftover of 8e-05.
