We look at the division of 28440815 by 796 
The aim is to understand the frequency of 796 in 28440815.

Going ahead to step 1:
When dividing 2 by 796, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 796

Advancing to step 2:
796 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 796

On to step 3:
796 goes into 284 0 times with a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 284 after subtracting 0 from 284.
Append the next digit (4) from the dividend to 284 and continue with: 2844 / 796

Step 4:
796 goes into 2844 3 times with a remainder of 456.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2388 away from 2844, we end up with 456.
Include the next digit (0) from the dividend after 456, then repeat: 4560 / 796

Moving on to step 5:
The number 796 fits into 4560 5 times, leaving a remainder of 580.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 3980 away from 4560, we end up with 580.
Bring next digit (8) of the dividend behind the 580 and repeat the process: 5808 / 796

Step 6:
The number 796 fits into 5808 7 times, leaving a remainder of 236.
Use 7 as the next digit of our solution. 
Result so far: 357.0
Deduct 5572 from 5808 and we're left with 236.
Fetch the next digit (1) from the dividend, attach it to 236 and continue: 2361 / 796

On to step 7:
The number 796 fits into 2361 2 times, leaving a remainder of 769.
The number 2 becomes the next digit in our result. 
Result so far: 3572.0
Deduct 1592 from 2361 and we're left with 769.
Take the next digit (5) from the dividend and append it to 769, then repeat: 7695 / 796

On to step 8:
When dividing 7695 by 796, we get 9 with a remainder of 531.
Put 9 as the next digit of the answer. 
Result so far: 35729.0
Subtract 7164 from 7695 to get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 9:
796 goes into 5310 6 times with a remainder of 534.
Write down 6 as next digit of the result. 
Result so far: 35729.6
If we subtract 4776 from 5310, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 10:
The number 796 fits into 5340 6 times, leaving a remainder of 564.
The next digit of our result is 6. 
Result so far: 35729.66
Deduct 4776 from 5340 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

After the division, we end up with 35729.66 and a remainder of 0.564.
