We look at the division of 8165292 by 66 
The aim is to understand the frequency of 66 in 8165292.

Let's proceed to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 66

Let's proceed to step 2:
The number 66 fits into 81 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 66 from 81, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 66

Step 3:
66 goes into 156 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 132 from 156, we get 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 66

Let's proceed to step 4:
The number 66 fits into 245 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 123.0
Subtract 198 from 245 to get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 66

Going ahead to step 5:
When dividing 472 by 66, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1237.0
If we take 462 away from 472, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 66

Let's proceed to step 6:
The number 66 fits into 109 1 times, leaving a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 12371.0
If we take 66 away from 109, we end up with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 66

Moving on to step 7:
66 can be fit into 432 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 123716.0
If we take 396 away from 432, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
360 divided by 66 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 123716.5
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 123716.54
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 123716.545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 123716.5454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 123716.54545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 123716.545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
360 divided by 66 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 123716.5454545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
300 divided by 66 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 123716.54545454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 123716.54545454, with a leftover of 3.6e-08.
