We're dividing 23886 by 81 
We want to figure out the number of times 23886 can be divided by 81.

Step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 81

Step 2:
81 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 81

Step 3:
If we divide 238 by 81, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 162 away from 238, we end up with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 81

On to step 4:
81 can be fit into 768 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 729 from 768 to get 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 81

Advancing to step 5:
If we divide 396 by 81, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
If we subtract 324 from 396, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 6:
81 can be fit into 720 8 times, resulting in a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 294.8
If we take 648 away from 720, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
81 goes into 720 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 294.88
The remainder is 72 after subtracting 648 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 294.88, with a leftover of 0.072.
