Let's divide 690024 by 18
Our goal is to divide 690024 by 18.

Going ahead to step 1:
18 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 18

Advancing to step 2:
18 goes into 69 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 54 from 69 to get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 18

Going ahead to step 3:
18 goes into 150 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 144 from 150 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 18

Let's proceed to step 4:
60 divided by 18 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 383.0
Subtract 54 from 60 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 18

Going ahead to step 5:
If we divide 62 by 18, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3833.0
Subtracting 54 from 62 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 18

Moving on to step 6:
When dividing 84 by 18, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 38334.0
Deduct 72 from 84 and we're left 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.

Step 7:
18 goes into 120 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 38334.6
If we take 108 away from 120, we end up 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.

Let's proceed to step 8:
120 divided by 18 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 38334.66
The remainder is 12 after subtracting 108 from 120.
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 result is 38334.66 with a remainder of 0.012.
