We're dividing 654886 by 28 
The aim is to understand the frequency of 28 in 654886.

Going ahead to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 28

Let's proceed to step 2:
28 can be fit into 65 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 56 from 65 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 28

Advancing to step 3:
94 divided by 28 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 28

Let's proceed to step 4:
108 divided by 28 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 233.0
If we subtract 84 from 108, we get 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 28

Advancing to step 5:
248 divided by 28 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2338.0
If we take 224 away from 248, we end up with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 28

Advancing to step 6:
28 goes into 246 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 23388.0
The remainder is 22 after subtracting 224 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
28 can be fit into 220 7 times, resulting in a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 23388.7
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 23388.78
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 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 23388.785
Subtracting 140 from 160 leaves us 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 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 23388.7857
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.

Let's proceed to step 11:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 23388.78571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 23388.785714
Deduct 112 from 120 and we're left 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.

Moving on to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 23388.7857142
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.

Advancing to step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 23388.78571428
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.

In conclusion, the division gives 23388.78571428 with a balance of 1.6e-08.
