133553 ÷ 12 
We're looking to find how many times 12 goes into 133553.

Going ahead to step 1:
1 divided by 12 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 12

On to step 2:
13 divided by 12 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 13, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 12

On to step 3:
The number 12 fits into 13 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Step 4:
When dividing 15 by 12, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
The remainder is 3 after subtracting 12 from 15.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Moving on to step 5:
12 can be fit into 35 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 1112.0
If we subtract 24 from 35, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

On to step 6:
If we divide 113 by 12, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 11129.0
If we take 108 away from 113, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 11129.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 11129.41
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.

On to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 11129.416
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 11129.4166
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.

The final result is 11129.4166 with a remainder of 8e-05.
