We look at the division of 62329128 by 221 
The aim is to understand the frequency of 221 in 62329128.

Step 1:
If we divide 6 by 221, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 221

Advancing to step 2:
When dividing 62 by 221, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 221

On to step 3:
623 divided by 221 is 2 with a remainder of 181.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 442 from 623 and we're left with 181.
Fetch the next digit (2) from the dividend, attach it to 181 and continue: 1812 / 221

Going ahead to step 4:
1812 divided by 221 is 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 1768 from 1812 and we're left with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 221

Advancing to step 5:
221 can be fit into 449 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
Deduct 442 from 449 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 221

Going ahead to step 6:
71 divided by 221 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 2820.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 221

Moving on to step 7:
If we divide 712 by 221, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 28203.0
Subtract 663 from 712 to get 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 221

Step 8:
The number 221 fits into 498 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 282032.0
Subtract 442 from 498 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
When dividing 560 by 221, we get 2 with a remainder of 118.
The next digit of our result is 2. 
Result so far: 282032.2
Subtract 442 from 560 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
221 goes into 1180 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 282032.25
The remainder is 75 after subtracting 1105 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
If we divide 750 by 221, we get 3 and a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 282032.253
If we take 663 away from 750, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 12:
221 can be fit into 870 3 times, resulting in a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 282032.2533
The remainder is 207 after subtracting 663 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 282032.2533 and a remainder of 0.00207.
