49155241 ÷ 221 
The aim is to understand the frequency of 221 in 49155241.

Advancing to step 1:
When dividing 4 by 221, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 221

Going ahead to step 2:
49 divided by 221 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 221

Going ahead to step 3:
The number 221 fits into 491 2 times, leaving a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 442 from 491, we get 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 221

Step 4:
When dividing 495 by 221, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 442 from 495 and we're left with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 221

Let's proceed to step 5:
221 can be fit into 535 2 times, resulting in a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Deduct 442 from 535 and we're left with 93.
Grab the next digit (2) from the dividend, add it to 93, then carry on: 932 / 221

On to step 6:
221 goes into 932 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 2224.0
Subtract 884 from 932 to get 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 221

Let's proceed to step 7:
If we divide 484 by 221, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 22242.0
If we take 442 away from 484, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 221

On to step 8:
221 can be fit into 421 1 times, resulting in a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 222421.0
If we subtract 221 from 421, 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.

Moving on to step 9:
2000 divided by 221 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 222421.9
Subtract 1989 from 2000 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
221 can be fit into 110 0 times, resulting in a remainder of 110.
The next digit of our result is 0. 
Result so far: 222421.9
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
1100 divided by 221 is 4 with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 222421.904
Subtracting 884 from 1100 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
When dividing 2160 by 221, we get 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 222421.9049
Subtract 1989 from 2160 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 13:
If we divide 1710 by 221, we get 7 and a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 222421.90497
If we subtract 1547 from 1710, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 14:
When dividing 1630 by 221, we get 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 222421.904977
If we subtract 1547 from 1630, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 222421.904977 with a remaining 8.3e-06.
