Let's divide 690247 by 18
The aim is to understand the frequency of 18 in 690247.

Step 1:
18 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
18 goes into 69 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 15 after subtracting 54 from 69.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 18

Step 3:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we subtract 144 from 150, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 18

On to step 4:
When dividing 62 by 18, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 383.0
The remainder is 8 after subtracting 54 from 62.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 18

Step 5:
18 goes into 84 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3834.0
Deduct 72 from 84 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 18

Advancing to step 6:
When dividing 127 by 18, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 38347.0
If we subtract 126 from 127, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 18, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 38347.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 38347.05
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 38347.055
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 38347.055, and the remainder is 0.001.
