We look at the division of 304476 by 220 
The aim is to understand the frequency of 220 in 304476.

On to step 1:
220 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 220

On to step 2:
When dividing 30 by 220, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 220

Moving on to step 3:
The number 220 fits into 304 1 times, leaving a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 220 from 304 and we're left with 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 220

Step 4:
When dividing 844 by 220, we get 3 with a remainder of 184.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 660 from 844 leaves us with 184.
Take the next digit (7) from the dividend and append it to 184, then repeat: 1847 / 220

Advancing to step 5:
220 can be fit into 1847 8 times, resulting in a remainder of 87.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 1760 from 1847 leaves us with 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 220

Going ahead to step 6:
When dividing 876 by 220, we get 3 with a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 1383.0
If we subtract 660 from 876, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 7:
If we divide 2160 by 220, we get 9 and a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 1383.9
If we subtract 1980 from 2160, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 8:
The number 220 fits into 1800 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1383.98
If we take 1760 away from 1800, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 220 is 1 with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 1383.981
The remainder is 180 after subtracting 220 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
The number 220 fits into 1800 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 1383.9818
If we take 1760 away from 1800, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 220 fits into 400 1 times, leaving a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 1383.98181
Subtract 220 from 400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
If we divide 1800 by 220, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1383.981818
If we subtract 1760 from 1800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
220 goes into 400 1 times with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 1383.9818181
If we subtract 220 from 400, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
1800 divided by 220 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1383.98181818
If we subtract 1760 from 1800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 1383.98181818, and the remainder is 4e-08.
