485228 divided by 28 
The aim is to understand the frequency of 28 in 485228.

Step 1:
4 divided by 28 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 28

Let's proceed to step 2:
The number 28 fits into 48 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 28 away from 48, we end up with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 28

Moving on to step 3:
The number 28 fits into 205 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 196 away from 205, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 28

Going ahead to step 4:
28 goes into 92 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Deduct 84 from 92 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 28

Step 5:
82 divided by 28 is 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1732.0
The remainder is 26 after subtracting 56 from 82.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 28

Step 6:
If we divide 268 by 28, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 17329.0
If we take 252 away from 268, we end up 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.

On to step 7:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17329.5
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 17329.57
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 9:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 17329.571
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.

Advancing to step 10:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17329.5714
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.

Step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17329.57142
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.

Going ahead to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 17329.571428
If we take 224 away from 240, we end up 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 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17329.5714285
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.

On to step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17329.57142857
Subtracting 196 from 200 leaves us 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.

In conclusion, the division gives 17329.57142857 with a balance of 4e-09.
