Let's divide 159371 by 12
We're looking to find how many times 12 goes into 159371.

Step 1:
12 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Advancing to step 2:
The number 12 fits into 15 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 12 from 15 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 12

Moving on to step 3:
When dividing 39 by 12, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 36 from 39 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Let's proceed to step 4:
12 goes into 33 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 132.0
The remainder is 9 after subtracting 24 from 33.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

On to step 5:
12 goes into 97 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 1328.0
If we subtract 96 from 97, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 12

Step 6:
12 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 13280.0
If we take 0 away from 11, we end up with 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:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 13280.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 13280.91
If we take 12 away from 20, 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.

On to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13280.916
Deduct 72 from 80 and we're left 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.

Going ahead to step 10:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 13280.9166
Subtracting 72 from 80 leaves us 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.

Our division results in 13280.9166 with a remaining 8e-05.
