595805 ÷ 28 
The aim is to understand the frequency of 28 in 595805.

On to step 1:
5 divided by 28 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 28

Step 2:
If we divide 59 by 28, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 56 from 59 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 28

Going ahead to step 3:
When dividing 35 by 28, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 28 from 35, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 28

Going ahead to step 4:
28 can be fit into 78 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 212.0
The remainder is 22 after subtracting 56 from 78.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 28

Advancing to step 5:
220 divided by 28 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 2127.0
If we subtract 196 from 220, we get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 28

Moving on to step 6:
28 can be fit into 245 8 times, resulting in a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 21278.0
Deduct 224 from 245 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 28, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 21278.7
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
28 can be fit into 140 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21278.75
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
28 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21278.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21278.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 21278.75 and a remainder of 0.0.
