782810 ÷ 28 
The aim is to understand the frequency of 28 in 782810.

Going ahead to step 1:
The number 28 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 28

Going ahead to step 2:
28 goes into 78 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 56 from 78, we get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 28

Moving on to step 3:
When dividing 222 by 28, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 26 after subtracting 196 from 222.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 28

Step 4:
When dividing 268 by 28, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
The remainder is 16 after subtracting 252 from 268.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 28

Going ahead to step 5:
If we divide 161 by 28, we get 5 and a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 2795.0
Deduct 140 from 161 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 28

Going ahead to step 6:
28 goes into 210 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 27957.0
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.

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: 27957.5
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.

Step 8:
When dividing 0 by 28, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27957.5
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.

Let's proceed to step 9:
0 divided by 28 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27957.5
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 27957.5 and a remainder of 0.0.
