We look at the division of 133729 by 12 
We're looking to find how many times 12 goes into 133729.

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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 12

Going ahead to step 2:
13 divided by 12 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 12 from 13, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 12

On to step 3:
The number 12 fits into 13 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 12 away from 13, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Step 4:
12 can be fit into 17 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Deduct 12 from 17 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Let's proceed to step 5:
When dividing 52 by 12, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 1114.0
Subtract 48 from 52 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 12

Going ahead to step 6:
When dividing 49 by 12, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 11144.0
Deduct 48 from 49 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11144.0
The remainder is 10 after subtracting 0 from 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:
When dividing 100 by 12, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11144.08
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.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 11144.083
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.

Step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 11144.0833
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.

After the division, we end up with 11144.0833 and a remainder of 4e-05.
