609878 divided by 28 
The aim is to understand the frequency of 28 in 609878.

Moving on to step 1:
The number 28 fits into 6 0 times, leaving 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.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 28

Let's proceed to step 2:
When dividing 60 by 28, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 56 from 60 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 28

Going ahead to step 3:
If we divide 49 by 28, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 28 from 49, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 28

Going ahead to step 4:
218 divided by 28 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 217.0
Subtract 196 from 218 to get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 28

On to step 5:
227 divided by 28 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 2178.0
If we subtract 224 from 227, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 28

Let's proceed to step 6:
When dividing 38 by 28, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21781.0
Subtract 28 from 38 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 28 fits into 100 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 21781.3
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 21781.35
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.

Advancing to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 21781.357
If we take 196 away from 200, we end up 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.

Let's proceed to step 10:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 21781.3571
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.

Going ahead to step 11:
120 divided by 28 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 21781.35714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 21781.357142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 21781.3571428
Subtracting 224 from 240 leaves us 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.

Going ahead to step 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 21781.35714285
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.

The final result is 21781.35714285 with a remainder of 2e-08.
