We're dividing 109866 by 8 
We're looking to find how many times 8 goes into 109866.

Moving on to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 8

Let's proceed to step 2:
The number 8 fits into 10 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 8 from 10, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 8

Going ahead to step 3:
The number 8 fits into 29 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 24 from 29 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 8

On to step 4:
8 goes into 58 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 56 from 58 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

Going ahead to step 5:
26 divided by 8 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 1373.0
Subtract 24 from 26 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 8

Advancing to step 6:
When dividing 26 by 8, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13733.0
Subtract 24 from 26 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
8 goes into 20 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 13733.2
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
8 goes into 40 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13733.25
Deduct 40 from 40 and we're left with 0.
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:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13733.25
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.

Going ahead to step 10:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13733.25
Subtracting 0 from 0 leaves us with 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 outcome is 13733.25, with a leftover of 0.0.
