We look at the division of 611474 by 221 
The aim is to understand the frequency of 221 in 611474.

Moving on to step 1:
221 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 221

Step 2:
221 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 221

On to step 3:
221 goes into 611 2 times with a remainder of 169.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 442 from 611 leaves us with 169.
Grab the next digit (4) from the dividend, add it to 169, then carry on: 1694 / 221

Moving on to step 4:
When dividing 1694 by 221, we get 7 with a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 1547 from 1694, we get 147.
Fetch the next digit (7) from the dividend, attach it to 147 and continue: 1477 / 221

Going ahead to step 5:
1477 divided by 221 is 6 with a remainder of 151.
Put 6 as the next digit of the answer. 
Result so far: 276.0
Subtracting 1326 from 1477 leaves us with 151.
Take the next digit (4) from the dividend and append it to 151, then repeat: 1514 / 221

Step 6:
221 can be fit into 1514 6 times, resulting in a remainder of 188.
The next digit of our result is 6. 
Result so far: 2766.0
The remainder is 188 after subtracting 1326 from 1514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 7:
The number 221 fits into 1880 8 times, leaving a remainder of 112.
The next digit of our result is 8. 
Result so far: 2766.8
Subtract 1768 from 1880 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 8:
When dividing 1120 by 221, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2766.85
Subtract 1105 from 1120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
If we divide 150 by 221, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 2766.85
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
The number 221 fits into 1500 6 times, leaving a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 2766.8506
Subtract 1326 from 1500 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 11:
221 goes into 1740 7 times with a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 2766.85067
Subtract 1547 from 1740 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 12:
The number 221 fits into 1930 8 times, leaving a remainder of 162.
The next digit of our result is 8. 
Result so far: 2766.850678
If we take 1768 away from 1930, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 13:
If we divide 1620 by 221, we get 7 and a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 2766.8506787
The remainder is 73 after subtracting 1547 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 14:
When dividing 730 by 221, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 2766.85067873
If we take 663 away from 730, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 2766.85067873, with a leftover of 6.7e-08.
