863855 ÷ 18 
Let's see how many times 18 fits into 863855.

Advancing to step 1:
18 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 18

Going ahead to step 2:
86 divided by 18 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 18

Step 3:
18 can be fit into 143 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 126 from 143 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 18

Advancing to step 4:
178 divided by 18 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 479.0
Subtract 162 from 178 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 18

Step 5:
If we divide 165 by 18, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 4799.0
Subtracting 162 from 165 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 18

On to step 6:
When dividing 35 by 18, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 47991.0
Subtracting 18 from 35 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
18 goes into 170 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 47991.9
Deduct 162 from 170 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.

Going ahead to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 47991.94
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 18, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 47991.944
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.

In conclusion, the division gives 47991.944 with a balance of 0.0008.
