We're dividing 136291 by 12 
Let's see how many times 12 fits into 136291.

Step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 12

On to step 2:
If we divide 13 by 12, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 12 from 13 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 12

Advancing to step 3:
12 can be fit into 16 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 12 away from 16, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Moving on to step 4:
12 can be fit into 42 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Deduct 36 from 42 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 12

Step 5:
When dividing 69 by 12, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 1135.0
If we subtract 60 from 69, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Step 6:
The number 12 fits into 91 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 11357.0
Subtract 84 from 91 to 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.

Going ahead to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11357.5
Subtracting 60 from 70 leaves us with 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:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11357.58
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.

Advancing to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 11357.583
The remainder is 4 after subtracting 36 from 40.
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:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 11357.5833
Deduct 36 from 40 and we're left 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.

In conclusion, the division gives 11357.5833 with a balance of 4e-05.
