198468 divided by 66 
The aim is to understand the frequency of 66 in 198468.

Going ahead to step 1:
1 divided by 66 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 66

Advancing to step 2:
66 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 66

Step 3:
198 divided by 66 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 198 from 198 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 66

Going ahead to step 4:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 4, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 66

Going ahead to step 5:
46 divided by 66 is 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 300.0
The remainder is 46 after subtracting 0 from 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 66

Moving on to step 6:
When dividing 468 by 66, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution.

Let's proceed to step 9:
When dividing 60 by 66, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3007.09
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 66, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 3007.0909
If we subtract 594 from 600, we 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.

Moving on to step 11:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3007.0909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
66 goes into 600 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3007.090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 3007.090909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
If we divide 600 by 66, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 3007.09090909
If we subtract 594 from 600, we 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.

Our division results in 3007.09090909 with a remaining 6e-09.
