Let's divide 261863 by 12
Let's see how many times 12 fits into 261863.

On to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Advancing to step 2:
12 can be fit into 26 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 12

On to step 3:
12 goes into 21 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 9 after subtracting 12 from 21.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

Step 4:
The number 12 fits into 98 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 218.0
Subtracting 96 from 98 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Let's proceed to step 5:
12 goes into 26 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2182.0
Subtract 24 from 26 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Let's proceed to step 6:
23 divided by 12 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 21821.0
If we subtract 12 from 23, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
12 goes into 110 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 21821.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
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: 21821.91
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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 21821.916
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.

On to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 21821.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 21821.9166 with a balance of 8e-05.
