We look at the division of 693002 by 18 
The aim is to understand the frequency of 18 in 693002.

Advancing to step 1:
18 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 18

Advancing to step 2:
When dividing 69 by 18, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 54 from 69 and we're left with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 18

Advancing to step 3:
153 divided by 18 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 144 from 153, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 18

On to step 4:
18 can be fit into 90 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 385.0
The remainder is 0 after subtracting 90 from 90.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 18

Going ahead to step 5:
When dividing 0 by 18, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3850.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 18

Step 6:
When dividing 2 by 18, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 38500.0
Deduct 0 from 2 and we're left 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.
Write down 1 as next digit of the result. 
Result so far: 38500.1
If we subtract 18 from 20, we 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.

Advancing to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 38500.11
If we take 18 away from 20, we end up 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.

Our division results in 38500.11 with a remaining 0.002.
