867909 divided by 18 
We're looking to find how many times 18 goes into 867909.

Going ahead to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 18

Going ahead to step 2:
The number 18 fits into 86 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 18

Moving on to step 3:
18 can be fit into 147 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 144 from 147 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 18

Let's proceed to step 4:
The number 18 fits into 39 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 482.0
Subtracting 36 from 39 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 18

On to step 5:
If we divide 30 by 18, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 4821.0
If we subtract 18 from 30, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 18

Let's proceed to step 6:
18 goes into 129 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 48217.0
If we subtract 126 from 129, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
18 can be fit into 30 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 48217.1
Subtract 18 from 30 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 48217.16
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 48217.166
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 48217.166, and the remainder is 0.0012.
