Let's divide 326850 by 66
The aim is to understand the frequency of 66 in 326850.

Advancing to step 1:
3 divided by 66 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 66

Step 2:
32 divided by 66 is 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 66

Moving on to step 3:
66 can be fit into 326 4 times, resulting in a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 264 from 326, we get 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 66

Advancing to step 4:
66 goes into 628 9 times with a remainder of 34.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 594 from 628 to get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 66

Advancing to step 5:
345 divided by 66 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
If we subtract 330 from 345, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 66

Let's proceed to step 6:
The number 66 fits into 150 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4952.0
Subtracting 132 from 150 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
66 goes into 180 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 4952.2
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 4952.27
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
If we divide 180 by 66, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 4952.272
The remainder is 48 after subtracting 132 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 66 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 4952.2727
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
180 divided by 66 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 4952.27272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 66, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 4952.272727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
66 goes into 180 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 4952.2727272
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
480 divided by 66 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 4952.27272727
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 4952.27272727, with a leftover of 1.8e-08.
