We look at the division of 260685 by 12 
We're looking to find how many times 12 goes into 260685.

Step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 12

Going ahead to step 2:
The number 12 fits into 26 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 2 after subtracting 24 from 26.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 12

Let's proceed to step 3:
20 divided by 12 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 12 from 20, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Moving on to step 4:
12 can be fit into 86 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
Subtract 84 from 86 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Advancing to step 5:
The number 12 fits into 28 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2172.0
If we subtract 24 from 28, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 12

Advancing to step 6:
When dividing 45 by 12, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 21723.0
Subtracting 36 from 45 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 21723.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21723.75
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.

Going ahead to step 9:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21723.75
If we subtract 0 from 0, we 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.

Moving on to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21723.75
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 final result is 21723.75 with a remainder of 0.0.
