We look at the division of 974274 by 28 
The aim is to understand the frequency of 28 in 974274.

Going ahead to step 1:
The number 28 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 28

On to step 2:
28 goes into 97 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 84 from 97 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 28

Advancing to step 3:
28 goes into 134 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 112 from 134, we get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 28

Step 4:
If we divide 222 by 28, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 347.0
Subtract 196 from 222 to get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 28

On to step 5:
When dividing 267 by 28, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 3479.0
Deduct 252 from 267 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 28

Advancing to step 6:
If we divide 154 by 28, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 34795.0
The remainder is 14 after subtracting 140 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 34795.5
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 28 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34795.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 28 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34795.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 34795.5 with a remainder of 0.0.
