Let's divide 563452 by 28
The aim is to understand the frequency of 28 in 563452.

Advancing to step 1:
28 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 28

Moving on to step 2:
If we divide 56 by 28, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 56 from 56 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 28

Let's proceed to step 3:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 28

Advancing to step 4:
28 goes into 34 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
The remainder is 6 after subtracting 28 from 34.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 28

On to step 5:
28 can be fit into 65 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2012.0
Subtracting 56 from 65 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 28

Step 6:
The number 28 fits into 92 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 20123.0
If we subtract 84 from 92, we 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 7:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 20123.2
Deduct 56 from 80 and we're left with 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 8:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 20123.28
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 20123.285
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 20123.2857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 20123.28571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20123.285714
If we take 112 away from 120, we end up 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.

Going ahead to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 20123.2857142
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.

Step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 20123.28571428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 20123.28571428, and the remainder is 1.6e-08.
