We look at the division of 975301 by 28 
The aim is to understand the frequency of 28 in 975301.

On to step 1:
The number 28 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 28

Step 2:
When dividing 97 by 28, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 84 from 97 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 28

Advancing to step 3:
135 divided by 28 is 4 with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 112 from 135 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 28

Step 4:
The number 28 fits into 233 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 348.0
If we take 224 away from 233, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 28

Let's proceed to step 5:
When dividing 90 by 28, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3483.0
If we take 84 away from 90, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 28

Advancing to step 6:
When dividing 61 by 28, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 34832.0
If we subtract 56 from 61, we get 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:
When dividing 50 by 28, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 34832.1
The remainder is 22 after subtracting 28 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
220 divided by 28 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 34832.17
Subtract 196 from 220 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.

Step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 34832.178
Subtract 224 from 240 to 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.
Put 5 as the next digit of the answer. 
Result so far: 34832.1785
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.

Step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 34832.17857
If we take 196 away from 200, we end up 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.

Let's proceed to step 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 34832.178571
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.

Going ahead to step 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 34832.1785714
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.

Going ahead to step 14:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 34832.17857142
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.

The final result is 34832.17857142 with a remainder of 2.4e-08.
