217884 ÷ 18 
We want to divide 217884 by 18.

Going ahead to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 18

Advancing to step 2:
18 can be fit into 21 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 18 away from 21, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 18

Moving on to step 3:
18 can be fit into 37 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 36 from 37 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 18

Let's proceed to step 4:
If we divide 18 by 18, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we take 18 away from 18, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 18

Advancing to step 5:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 1210.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 18

Going ahead to step 6:
When dividing 84 by 18, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 12104.0
Subtract 72 from 84 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.

Advancing to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12104.6
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.

Going ahead to step 8:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12104.66
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 final outcome is 12104.66, with a leftover of 0.012.
