213864 divided by 18 
We want to figure out the number of times 213864 can be divided by 18.

Going ahead to step 1:
2 divided by 18 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 18

On to step 2:
18 goes into 21 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 18 from 21 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

Going ahead to step 3:
The number 18 fits into 33 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 18 from 33 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 18

Advancing to step 4:
18 can be fit into 158 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
The remainder is 14 after subtracting 144 from 158.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 18

Step 5:
18 can be fit into 146 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 1188.0
If we take 144 away from 146, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 18

Let's proceed to step 6:
18 goes into 24 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11881.0
Subtract 18 from 24 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 11881.3
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
18 goes into 60 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 11881.33
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 11881.33, and the remainder is 0.006.
