We look at the division of 66023813 by 220 
The aim is to understand the frequency of 220 in 66023813.

Moving on to step 1:
220 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 220

Step 2:
220 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 220

Going ahead to step 3:
220 goes into 660 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 0 after subtracting 660 from 660.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 220

Moving on to step 4:
220 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 220

Going ahead to step 5:
220 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 300.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 220

Step 6:
220 goes into 238 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3001.0
Subtract 220 from 238 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 220

Let's proceed to step 7:
181 divided by 220 is 0 with a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 30010.0
Deduct 0 from 181 and we're left with 181.
Fetch the next digit (3) from the dividend, attach it to 181 and continue: 1813 / 220

On to step 8:
1813 divided by 220 is 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 300108.0
If we subtract 1760 from 1813, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
If we divide 530 by 220, we get 2 and a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 300108.2
Deduct 440 from 530 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
If we divide 900 by 220, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 300108.24
The remainder is 20 after subtracting 880 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 220, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 300108.24
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
2000 divided by 220 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 300108.2409
If we subtract 1980 from 2000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
220 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 300108.2409
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
220 can be fit into 2000 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 300108.240909
Deduct 1980 from 2000 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
If we divide 200 by 220, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 300108.240909
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
220 can be fit into 2000 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 300108.24090909
If we take 1980 away from 2000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 300108.24090909, with a leftover of 2e-08.
