We're dividing 545878 by 28 
The aim is to understand the frequency of 28 in 545878.

Moving on to step 1:
When dividing 5 by 28, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 28

Step 2:
28 can be fit into 54 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 28 from 54, we get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 28

Advancing to step 3:
265 divided by 28 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 252 from 265 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 28

Let's proceed to step 4:
138 divided by 28 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
Subtract 112 from 138 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 28

On to step 5:
The number 28 fits into 267 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 1949.0
Subtract 252 from 267 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 28

Let's proceed to step 6:
28 goes into 158 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 19495.0
Deduct 140 from 158 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
28 goes into 180 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 19495.6
If we subtract 168 from 180, we 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.

Let's proceed to step 8:
120 divided by 28 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 19495.64
Subtracting 112 from 120 leaves us 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.

Let's proceed to step 9:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 19495.642
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.

Step 10:
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: 19495.6428
Subtract 224 from 240 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.

Going ahead to step 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 19495.64285
Subtract 140 from 160 to 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.

Moving on to step 12:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 19495.642857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 19495.6428571
If we subtract 28 from 40, we 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.

Going ahead to step 14:
28 goes into 120 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 19495.64285714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 19495.64285714 with a remaining 8e-09.
