We look at the division of 636206 by 12 
We want to divide 636206 by 12.

Moving on to step 1:
6 divided by 12 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 12

On to step 2:
The number 12 fits into 63 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 60 from 63 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 12

Advancing to step 3:
If we divide 36 by 12, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 36 from 36 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 12

Moving on to step 4:
When dividing 2 by 12, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 530.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 12

Moving on to step 5:
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: 5301.0
Subtracting 12 from 20 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 12

On to step 6:
The number 12 fits into 86 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 53017.0
The remainder is 2 after subtracting 84 from 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 53017.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 53017.16
If we take 72 away from 80, we end up 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.

Let's proceed to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 53017.166
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 outcome is 53017.166, with a leftover of 0.0008.
