563688 ÷ 28 
The aim is to understand the frequency of 28 in 563688.

Step 1:
28 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 28

Let's proceed to step 2:
28 goes into 56 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 56 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 28

Let's proceed to step 3:
The number 28 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 28

Going ahead to step 4:
28 can be fit into 36 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
The remainder is 8 after subtracting 28 from 36.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 28

Moving on to step 5:
When dividing 88 by 28, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2013.0
If we take 84 away from 88, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 28

Let's proceed to step 6:
28 goes into 48 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 20131.0
Subtracting 28 from 48 leaves us 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 7:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 20131.7
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.

Moving on to step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 20131.71
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.

Moving on to step 9:
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: 20131.714
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.

Going ahead to step 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 20131.7142
Subtracting 56 from 80 leaves us 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.

Moving on to step 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 20131.71428
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.

Step 12:
28 goes into 160 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 20131.714285
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.

Moving on to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 20131.7142857
If we take 196 away from 200, we end up 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.

Going ahead to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 20131.71428571
Deduct 28 from 40 and we're left 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.

After the division, we end up with 20131.71428571 and a remainder of 1.2e-08.
