Let's divide 236731 by 12
Let's see how many times 12 fits into 236731.

On to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 12

Let's proceed to step 2:
23 divided by 12 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 12 from 23.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 12

Going ahead to step 3:
12 can be fit into 116 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 108 from 116 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Let's proceed to step 4:
12 goes into 87 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 197.0
If we take 84 away from 87, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Advancing to step 5:
If we divide 33 by 12, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 1972.0
The remainder is 9 after subtracting 24 from 33.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Advancing to step 6:
12 goes into 91 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 19727.0
Subtracting 84 from 91 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19727.5
Subtract 60 from 70 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 8:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 19727.58
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.

Advancing to step 9:
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: 19727.583
Subtract 36 from 40 to 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 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 19727.5833
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 19727.5833 and a remainder of 4e-05.
