115660 ÷ 12 
Let's see how many times 12 fits into 115660.

Step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 12

Advancing to step 2:
12 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 12

On to step 3:
12 goes into 115 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 108 from 115 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 12

Let's proceed to step 4:
When dividing 76 by 12, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 4 after subtracting 72 from 76.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 12

Let's proceed to step 5:
When dividing 46 by 12, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 963.0
If we subtract 36 from 46, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 12

On to step 6:
100 divided by 12 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9638.0
If we take 96 away from 100, we end up 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.

Going ahead to step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 9638.3
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.

On to step 8:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 9638.33
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.

The final result is 9638.33 with a remainder of 0.004.
