We look at the division of 465524 by 18 
The aim is to understand the frequency of 18 in 465524.

Step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 18

Going ahead to step 2:
The number 18 fits into 46 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 36 from 46, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 18

Going ahead to step 3:
If we divide 105 by 18, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 15 after subtracting 90 from 105.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 18

Step 4:
155 divided by 18 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we subtract 144 from 155, we get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 18

Let's proceed to step 5:
18 can be fit into 112 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 2586.0
The remainder is 4 after subtracting 108 from 112.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 18

Advancing to step 6:
18 goes into 44 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 25862.0
The remainder is 8 after subtracting 36 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
18 goes into 80 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 25862.4
If we take 72 away from 80, we end up 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 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 25862.44
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.

After the division, we end up with 25862.44 and a remainder of 0.008.
