241688 ÷ 18 
We want to figure out the number of times 241688 can be divided by 18.

Going ahead to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 18

Going ahead to step 2:
If we divide 24 by 18, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 18 from 24.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 18

Moving on to step 3:
The number 18 fits into 61 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 54 away from 61, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 18

Going ahead to step 4:
18 can be fit into 76 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 4 after subtracting 72 from 76.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 18

Advancing to step 5:
18 can be fit into 48 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 1342.0
The remainder is 12 after subtracting 36 from 48.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

On to step 6:
18 can be fit into 128 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 13427.0
Subtracting 126 from 128 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 18, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 13427.1
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 13427.11
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 13427.11 with a remainder of 0.002.
