We divide 552452 by 28
The aim is to understand the frequency of 28 in 552452.

Going ahead to step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 28

Moving on to step 2:
28 goes into 55 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 28 away from 55, we end up with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 28

Advancing to step 3:
28 goes into 272 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 252 from 272 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 28

Step 4:
The number 28 fits into 204 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Deduct 196 from 204 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 28

On to step 5:
28 can be fit into 85 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 1973.0
If we take 84 away from 85, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

Let's proceed to step 6:
The number 28 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 19730.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 28 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 19730.4
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 19730.42
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 19730.428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 19730.4285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 19730.42857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 19730.428571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 19730.4285714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 19730.42857142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 19730.42857142, with a leftover of 2.4e-08.
