We look at the division of 47132549 by 221 
The aim is to understand the frequency of 221 in 47132549.

Step 1:
221 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 221

Advancing to step 2:
If we divide 47 by 221, we get 0 and a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 221

Going ahead to step 3:
When dividing 471 by 221, we get 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 29 after subtracting 442 from 471.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 221

Going ahead to step 4:
The number 221 fits into 293 1 times, leaving a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 221 from 293 to get 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 221

Let's proceed to step 5:
221 can be fit into 722 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we take 663 away from 722, we end up with 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 221

Going ahead to step 6:
221 goes into 595 2 times with a remainder of 153.
Record the quotient 2 as the next digit in the result. 
Result so far: 2132.0
The remainder is 153 after subtracting 442 from 595.
Fetch the next digit (4) from the dividend, attach it to 153 and continue: 1534 / 221

Step 7:
When dividing 1534 by 221, we get 6 with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 21326.0
If we take 1326 away from 1534, we end up with 208.
Include the next digit (9) from the dividend after 208, then repeat: 2089 / 221

Advancing to step 8:
If we divide 2089 by 221, we get 9 and a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 213269.0
Subtract 1989 from 2089 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
If we divide 1000 by 221, we get 4 and a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 213269.4
If we take 884 away from 1000, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
The number 221 fits into 1160 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 213269.45
Subtracting 1105 from 1160 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
221 can be fit into 550 2 times, resulting in a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 213269.452
If we take 442 away from 550, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
The number 221 fits into 1080 4 times, leaving a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 213269.4524
If we take 884 away from 1080, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 13:
The number 221 fits into 1960 8 times, leaving a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 213269.45248
If we subtract 1768 from 1960, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
1920 divided by 221 is 8 with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 213269.452488
If we take 1768 away from 1920, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The quotient of the division is 213269.452488, and the remainder is 1.52e-05.
