Let's divide 653772 by 18
The aim is to understand the frequency of 18 in 653772.

On 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.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 18

Step 2:
When dividing 65 by 18, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 54 from 65 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 18

Moving on to step 3:
If we divide 113 by 18, we get 6 and a remainder of 5.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 108 from 113 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 18

Moving on to step 4:
18 can be fit into 57 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 363.0
The remainder is 3 after subtracting 54 from 57.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 18

Advancing to step 5:
If we divide 37 by 18, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 3632.0
If we take 36 away from 37, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 18

Going ahead to step 6:
12 divided by 18 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 36320.0
Deduct 0 from 12 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 can be fit into 120 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 36320.6
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.

Step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 36320.66
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.

In conclusion, the division gives 36320.66 with a balance of 0.012.
