Let's divide 140338 by 12
We want to figure out the number of times 140338 can be divided by 12.

Going ahead to step 1:
12 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

Advancing to step 2:
When dividing 14 by 12, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 12 from 14 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Moving on to step 3:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 12 from 20 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

Step 4:
12 goes into 83 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 116.0
Deduct 72 from 83 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

On to step 5:
If we divide 113 by 12, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 1169.0
The remainder is 5 after subtracting 108 from 113.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

Advancing to step 6:
12 can be fit into 58 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 11694.0
Subtract 48 from 58 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 11694.8
Subtracting 96 from 100 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.

Moving on to step 8:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 11694.83
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.

Advancing to step 9:
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: 11694.833
If we take 36 away from 40, 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.

Our division results in 11694.833 with a remaining 0.0004.
