We look at the division of 866119 by 18 
We're looking to find how many times 18 goes into 866119.

Advancing to step 1:
When dividing 8 by 18, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 18

Going ahead to step 2:
When dividing 86 by 18, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 72 from 86 leaves us with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 18

Moving on to step 3:
When dividing 146 by 18, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 144 away from 146, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 18

On to step 4:
When dividing 21 by 18, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 481.0
Subtract 18 from 21 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 18

Let's proceed to step 5:
18 goes into 31 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 4811.0
If we take 18 away from 31, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 18

On to step 6:
18 can be fit into 139 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 48117.0
Subtract 126 from 139 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 48117.7
Deduct 126 from 130 and we're left with 4.
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:
When dividing 40 by 18, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 48117.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
18 goes into 40 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 48117.722
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 48117.722 with a balance of 0.0004.
