We're dividing 806502 by 18 
The aim is to understand the frequency of 18 in 806502.

Moving on to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 18

Advancing to step 2:
If we divide 80 by 18, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 72 from 80 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 18

On to step 3:
When dividing 86 by 18, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 72 from 86 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 18

Going ahead to step 4:
145 divided by 18 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 448.0
The remainder is 1 after subtracting 144 from 145.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 18

Advancing to step 5:
10 divided by 18 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4480.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 18

Step 6:
18 goes into 102 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 44805.0
Deduct 90 from 102 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.

On to step 7:
When dividing 120 by 18, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 44805.6
Deduct 108 from 120 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.

Let's proceed to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 44805.66
Deduct 108 from 120 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.

The final result is 44805.66 with a remainder of 0.012.
