We look at the division of 205995 by 12 
We're looking to find how many times 12 goes into 205995.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Moving on to step 2:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 12 from 20.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

Moving on to step 3:
The number 12 fits into 85 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 84 away from 85, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Let's proceed to step 4:
The number 12 fits into 19 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 12 from 19 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 12

Moving on to step 5:
79 divided by 12 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 1716.0
If we take 72 away from 79, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 12

Advancing to step 6:
75 divided by 12 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 17166.0
Subtract 72 from 75 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 17166.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 17166.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 17166.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17166.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 17166.25, and the remainder is 0.0.
