We look at the division of 799856 by 28 
The aim is to understand the frequency of 28 in 799856.

Let's proceed to step 1:
The number 28 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 28

Advancing to step 2:
When dividing 79 by 28, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 56 from 79 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 28

Moving on to step 3:
When dividing 239 by 28, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 224 from 239, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 28

Going ahead to step 4:
The number 28 fits into 158 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 285.0
Subtract 140 from 158 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 28

Moving on to step 5:
185 divided by 28 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 2856.0
Subtracting 168 from 185 leaves us with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 28

Let's proceed to step 6:
If we divide 176 by 28, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 28566.0
Subtracting 168 from 176 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 7:
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: 28566.2
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.

Moving on to step 8:
240 divided by 28 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 28566.28
Deduct 224 from 240 and we're left 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 9:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 28566.285
The remainder is 20 after subtracting 140 from 160.
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:
When dividing 200 by 28, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 28566.2857
Deduct 196 from 200 and we're left 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.

Advancing to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 28566.28571
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 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 28566.285714
If we take 112 away from 120, we end up 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 13:
28 goes into 80 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 28566.2857142
Subtract 56 from 80 to 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.

Advancing to step 14:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 28566.28571428
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.

The final result is 28566.28571428 with a remainder of 1.6e-08.
