278852 divided by 28 
The aim is to understand the frequency of 28 in 278852.

Let's proceed to step 1:
2 divided by 28 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 28

Moving on to step 2:
28 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 28

Advancing to step 3:
28 can be fit into 278 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 252 from 278, we get 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 28

Step 4:
28 can be fit into 268 9 times, resulting in a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 252 from 268 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 28

On to step 5:
When dividing 165 by 28, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 995.0
If we subtract 140 from 165, we get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 28

On to step 6:
28 goes into 252 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9959.0
The remainder is 0 after subtracting 252 from 252.
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 7:
28 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9959.0
If we take 0 away from 0, we end up 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.

Moving on to step 8:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9959.0
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.

After the division, we end up with 9959.0 and a remainder of 0.0.
