We divide 495558 by 28
The aim is to understand the frequency of 28 in 495558.

On to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 28

Moving on to step 2:
The number 28 fits into 49 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 28 from 49 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 28

Going ahead to step 3:
When dividing 215 by 28, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 196 from 215 leaves us with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 28

Moving on to step 4:
When dividing 195 by 28, we get 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Deduct 168 from 195 and we're left with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 28

Moving on to step 5:
If we divide 275 by 28, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 1769.0
Subtract 252 from 275 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 28

Let's proceed to step 6:
If we divide 238 by 28, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 17698.0
Subtracting 224 from 238 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
28 goes into 140 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17698.5
Deduct 140 from 140 and we're left 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.

Let's proceed to step 8:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17698.5
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.

On to step 9:
If we divide 0 by 28, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17698.5
If we subtract 0 from 0, we 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.

Our division results in 17698.5 with a remaining 0.0.
