Let's divide 156974 by 12
We want to figure out the number of times 156974 can be divided by 12.

On to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Moving on to step 2:
12 can be fit into 15 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 12 from 15.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

Let's proceed to step 3:
The number 12 fits into 36 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 36 from 36 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Going ahead to step 4:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Advancing to step 5:
12 can be fit into 97 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 1308.0
Subtract 96 from 97 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

Going ahead to step 6:
The number 12 fits into 14 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 13081.0
Deduct 12 from 14 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.

Going ahead to step 7:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 13081.1
Deduct 12 from 20 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.

Let's proceed to step 8:
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: 13081.16
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.

On to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13081.166
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.

The final result is 13081.166 with a remainder of 0.0008.
