We're dividing 60186649 by 221 
The aim is to understand the frequency of 221 in 60186649.

Going ahead to step 1:
When dividing 6 by 221, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 221

Moving on to step 2:
221 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 221

Step 3:
221 goes into 601 2 times with a remainder of 159.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 442 from 601 to get 159.
Fetch the next digit (8) from the dividend, attach it to 159 and continue: 1598 / 221

Moving on to step 4:
The number 221 fits into 1598 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 51 after subtracting 1547 from 1598.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 221

Step 5:
The number 221 fits into 516 2 times, leaving a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 272.0
Subtracting 442 from 516 leaves us with 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 221

Going ahead to step 6:
221 can be fit into 746 3 times, resulting in a remainder of 83.
The next digit of our result is 3. 
Result so far: 2723.0
If we take 663 away from 746, we end up with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 221

Step 7:
When dividing 834 by 221, we get 3 with a remainder of 171.
Write down 3 as next digit of the result. 
Result so far: 27233.0
Subtract 663 from 834 to get 171.
Grab the next digit (9) from the dividend, add it to 171, then carry on: 1719 / 221

On to step 8:
If we divide 1719 by 221, we get 7 and a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 272337.0
Deduct 1547 from 1719 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 9:
1720 divided by 221 is 7 with a remainder of 173.
Put 7 as the next digit of the answer. 
Result so far: 272337.7
Subtracting 1547 from 1720 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 10:
221 can be fit into 1730 7 times, resulting in a remainder of 183.
Put 7 as the next digit of the answer. 
Result so far: 272337.77
If we subtract 1547 from 1730, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

After the division, we end up with 272337.77 and a remainder of 0.183.
