218510 divided by 18 
Our goal is to divide 218510 by 18.

Moving on to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 18

Advancing to step 2:
When dividing 21 by 18, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 18

Let's proceed to step 3:
The number 18 fits into 38 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 36 from 38, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 18

Let's proceed to step 4:
25 divided by 18 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 18 from 25 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 18

Advancing to step 5:
71 divided by 18 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 1213.0
The remainder is 17 after subtracting 54 from 71.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 18

Going ahead to step 6:
The number 18 fits into 170 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 12139.0
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.

Let's proceed to step 7:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 12139.4
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 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 12139.44
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 12139.44 with a remainder of 0.008.
