62144772 ÷ 221 
The aim is to understand the frequency of 221 in 62144772.

On to step 1:
221 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 221

On to step 2:
221 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 221

Advancing to step 3:
221 goes into 621 2 times with a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 442 away from 621, we end up with 179.
Bring next digit (4) of the dividend behind the 179 and repeat the process: 1794 / 221

Moving on to step 4:
If we divide 1794 by 221, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 1768 from 1794 and we're left with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 221

Moving on to step 5:
The number 221 fits into 264 1 times, leaving a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 281.0
Subtract 221 from 264 to get 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 221

Let's proceed to step 6:
If we divide 437 by 221, we get 1 and a remainder of 216.
Record the quotient 1 as the next digit in the result. 
Result so far: 2811.0
Subtracting 221 from 437 leaves us with 216.
Include the next digit (7) from the dividend after 216, then repeat: 2167 / 221

Going ahead to step 7:
When dividing 2167 by 221, we get 9 with a remainder of 178.
Put 9 as the next digit of the answer. 
Result so far: 28119.0
The remainder is 178 after subtracting 1989 from 2167.
Include the next digit (2) from the dividend after 178, then repeat: 1782 / 221

Let's proceed to step 8:
1782 divided by 221 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 281198.0
Subtracting 1768 from 1782 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
The number 221 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 281198.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
When dividing 1400 by 221, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 281198.06
The remainder is 74 after subtracting 1326 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
740 divided by 221 is 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 281198.063
Subtracting 663 from 740 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
When dividing 770 by 221, we get 3 with a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 281198.0633
The remainder is 107 after subtracting 663 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 281198.0633 and a remainder of 0.00107.
