863805 divided by 18 
We're looking to find how many times 18 goes into 863805.

On to step 1:
8 divided by 18 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 18

Let's proceed to step 2:
When dividing 86 by 18, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 72 from 86 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 18

On to step 3:
143 divided by 18 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 126 from 143 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 18

Step 4:
The number 18 fits into 178 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 479.0
If we subtract 162 from 178, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 18

Let's proceed to step 5:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 4798.0
Subtract 144 from 160 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 18

Let's proceed to step 6:
18 goes into 165 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 47989.0
Subtracting 162 from 165 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 47989.1
If we take 18 away from 30, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 47989.16
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
18 goes into 120 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 47989.166
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 47989.166 with a balance of 0.0012.
