606830 ÷ 28 
The aim is to understand the frequency of 28 in 606830.

Moving on to step 1:
6 divided by 28 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 28

On to step 2:
The number 28 fits into 60 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 56 from 60.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 28

Moving on to step 3:
28 goes into 46 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 28 from 46 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 28

Going ahead to step 4:
The number 28 fits into 188 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Subtract 168 from 188 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 28

On to step 5:
When dividing 203 by 28, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 2167.0
Subtracting 196 from 203 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 28

Going ahead to step 6:
28 goes into 70 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 21672.0
The remainder is 14 after subtracting 56 from 70.
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 7:
28 can be fit into 140 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21672.5
Subtract 140 from 140 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 28, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21672.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21672.5
Subtracting 0 from 0 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.

The quotient of the division is 21672.5, and the remainder is 0.0.
