156979 divided by 12 
Let's see how many times 12 fits into 156979.

Moving 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
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Step 2:
12 can be fit into 15 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 12 from 15 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

Step 3:
12 goes into 36 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 36 from 36, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Let's proceed to step 4:
9 divided by 12 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

Advancing to step 5:
When dividing 97 by 12, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1308.0
If we take 96 away from 97, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 12

On to step 6:
19 divided by 12 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 13081.0
If we subtract 12 from 19, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13081.5
Subtract 60 from 70 to get 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 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13081.58
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 13081.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 13081.5833
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.

After the division, we end up with 13081.5833 and a remainder of 4e-05.
