We're dividing 769920 by 18 
The aim is to understand the frequency of 18 in 769920.

Advancing to step 1:
7 divided by 18 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 18

Moving on to step 2:
When dividing 76 by 18, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 4 after subtracting 72 from 76.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 18

Advancing to step 3:
18 can be fit into 49 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 36 from 49 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 18

Let's proceed to step 4:
18 goes into 139 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 427.0
If we take 126 away from 139, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 18

Step 5:
The number 18 fits into 132 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 4277.0
If we take 126 away from 132, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 18

Going ahead to step 6:
When dividing 60 by 18, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 42773.0
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 42773.3
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 18 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 42773.33
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 42773.33 with a remaining 0.006.
