220879 divided by 66 
The aim is to understand the frequency of 66 in 220879.

Moving on to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 66

Let's proceed to step 2:
66 goes into 22 0 times with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 66

Let's proceed to step 3:
If we divide 220 by 66, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 198 from 220 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 66

Going ahead to step 4:
If we divide 228 by 66, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 198 from 228 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 66

Advancing to step 5:
307 divided by 66 is 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
The remainder is 43 after subtracting 264 from 307.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 66

Moving on to step 6:
The number 66 fits into 439 6 times, leaving a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 3346.0
Deduct 396 from 439 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
66 goes into 430 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 3346.6
If we subtract 396 from 430, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3346.65
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 3346.651
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 66 fits into 340 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3346.6515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 66, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 3346.65151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3346.651515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 66, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3346.6515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
If we divide 340 by 66, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3346.65151515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 3346.65151515 with a remaining 1e-08.
