We look at the division of 933245 by 28 
The aim is to understand the frequency of 28 in 933245.

Going ahead to step 1:
The number 28 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 28

On to step 2:
28 goes into 93 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 84 from 93 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 28

On to step 3:
93 divided by 28 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 84 away from 93, we end up with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 28

Moving on to step 4:
If we divide 92 by 28, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 333.0
If we take 84 away from 92, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 28

Going ahead to step 5:
When dividing 84 by 28, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3333.0
Deduct 84 from 84 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 28

On to step 6:
If we divide 5 by 28, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 33330.0
Subtracting 0 from 5 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 28, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 33330.1
If we take 28 away from 50, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 28 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 33330.17
Deduct 196 from 220 and we're left 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.

Going ahead to step 9:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 33330.178
If we subtract 224 from 240, we 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.

Step 10:
160 divided by 28 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 33330.1785
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.

Advancing to step 11:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 33330.17857
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.

Advancing to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 33330.178571
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.

Step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 33330.1785714
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.

Step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 33330.17857142
Deduct 56 from 80 and we're left 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.

In conclusion, the division gives 33330.17857142 with a balance of 2.4e-08.
