Let's divide 53854138 by 221
The aim is to understand the frequency of 221 in 53854138.

Going ahead to step 1:
221 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 221

Step 2:
53 divided by 221 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 221

Going ahead to step 3:
538 divided by 221 is 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 442 from 538 leaves us with 96.
Take the next digit (5) from the dividend and append it to 96, then repeat: 965 / 221

Moving on to step 4:
965 divided by 221 is 4 with a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 884 from 965 and we're left with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 221

Step 5:
221 goes into 814 3 times with a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
The remainder is 151 after subtracting 663 from 814.
Append the next digit (1) from the dividend to 151 and continue with: 1511 / 221

On to step 6:
221 goes into 1511 6 times with a remainder of 185.
Write down 6 as next digit of the result. 
Result so far: 2436.0
Subtracting 1326 from 1511 leaves us with 185.
Take the next digit (3) from the dividend and append it to 185, then repeat: 1853 / 221

Step 7:
1853 divided by 221 is 8 with a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 24368.0
Deduct 1768 from 1853 and we're left with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 221

Let's proceed to step 8:
221 can be fit into 858 3 times, resulting in a remainder of 195.
Use 3 as the next digit of our solution. 
Result so far: 243683.0
If we take 663 away from 858, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
When dividing 1950 by 221, we get 8 with a remainder of 182.
The number 8 becomes the next digit in our result. 
Result so far: 243683.8
Subtract 1768 from 1950 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
221 goes into 1820 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 243683.88
Subtracting 1768 from 1820 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 243683.88 with a balance of 0.052.
