872297 ÷ 28 
The aim is to understand the frequency of 28 in 872297.

Step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 28

Moving on to step 2:
If we divide 87 by 28, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 84 from 87 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 28

On to step 3:
If we divide 32 by 28, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 28 away from 32, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 28

Going ahead to step 4:
The number 28 fits into 42 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Subtract 28 from 42 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 28

On to step 5:
The number 28 fits into 149 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 3115.0
If we take 140 away from 149, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 28

On to step 6:
97 divided by 28 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 31153.0
If we take 84 away from 97, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 28, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 31153.4
The remainder is 18 after subtracting 112 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
28 goes into 180 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 31153.46
Subtract 168 from 180 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 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 31153.464
Subtract 112 from 120 to 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.

Let's proceed to step 10:
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: 31153.4642
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 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 31153.46428
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.

Moving on to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 31153.464285
Deduct 140 from 160 and we're left 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.

On to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 31153.4642857
If we subtract 196 from 200, we get 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 14:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 31153.46428571
Deduct 28 from 40 and we're left 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.

The quotient of the division is 31153.46428571, and the remainder is 1.2e-08.
