14228729 ÷ 220 
The aim is to understand the frequency of 220 in 14228729.

Step 1:
When dividing 1 by 220, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 220

Step 2:
220 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 220

Step 3:
220 can be fit into 142 0 times, resulting in a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 142, we get 142.
Include the next digit (2) from the dividend after 142, then repeat: 1422 / 220

Step 4:
The number 220 fits into 1422 6 times, leaving a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 1320 from 1422 leaves us with 102.
Grab the next digit (8) from the dividend, add it to 102, then carry on: 1028 / 220

Advancing to step 5:
1028 divided by 220 is 4 with a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 880 from 1028 leaves us with 148.
Bring next digit (7) of the dividend behind the 148 and repeat the process: 1487 / 220

Going ahead to step 6:
When dividing 1487 by 220, we get 6 with a remainder of 167.
The next digit of our result is 6. 
Result so far: 646.0
If we subtract 1320 from 1487, we get 167.
Take the next digit (2) from the dividend and append it to 167, then repeat: 1672 / 220

Step 7:
If we divide 1672 by 220, we get 7 and a remainder of 132.
Put 7 as the next digit of the answer. 
Result so far: 6467.0
Deduct 1540 from 1672 and we're left with 132.
Take the next digit (9) from the dividend and append it to 132, then repeat: 1329 / 220

Moving on to step 8:
220 can be fit into 1329 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 64676.0
If we take 1320 away from 1329, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 220, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 64676.0
Deduct 0 from 90 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.

Advancing to step 10:
If we divide 900 by 220, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 64676.04
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.

Going ahead to step 11:
If we divide 200 by 220, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 64676.04
Subtracting 0 from 200 leaves us 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.

Advancing to step 12:
220 goes into 2000 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 64676.0409
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.

Step 13:
If we divide 200 by 220, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 64676.0409
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.

Going ahead to step 14:
If we divide 2000 by 220, we get 9 and a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 64676.040909
Subtracting 1980 from 2000 leaves us 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.

On to step 15:
200 divided by 220 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 64676.040909
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.

Advancing to step 16:
220 goes into 2000 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 64676.04090909
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.

After the division, we end up with 64676.04090909 and a remainder of 2e-08.
