80456 ÷ 28 
The aim is to understand the frequency of 28 in 80456.

Let's proceed to step 1:
28 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 28

Step 2:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 56 from 80 and we're left with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 28

Advancing to step 3:
The number 28 fits into 244 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 20 after subtracting 224 from 244.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 28

Moving on to step 4:
205 divided by 28 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 287.0
Subtract 196 from 205 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 28

On to step 5:
When dividing 96 by 28, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 2873.0
Subtract 84 from 96 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.

Going ahead to step 6:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2873.4
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.

Advancing to step 7:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2873.42
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2873.428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
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: 2873.4285
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.

Step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 2873.42857
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 11:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2873.428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 2873.4285714
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.

Going ahead to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2873.42857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2873.42857142 with a remainder of 2.4e-08.
