Let's divide 28646507 by 791
The aim is to understand the frequency of 791 in 28646507.

Moving on to step 1:
The number 791 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 791

Let's proceed to step 2:
28 divided by 791 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 791

Step 3:
If we divide 286 by 791, we get 0 and a remainder of 286.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 286, we get 286.
Bring next digit (4) of the dividend behind the 286 and repeat the process: 2864 / 791

Going ahead to step 4:
791 goes into 2864 3 times with a remainder of 491.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2373 from 2864, we get 491.
Fetch the next digit (6) from the dividend, attach it to 491 and continue: 4916 / 791

On to step 5:
791 can be fit into 4916 6 times, resulting in a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtracting 4746 from 4916 leaves us with 170.
Grab the next digit (5) from the dividend, add it to 170, then carry on: 1705 / 791

Step 6:
791 can be fit into 1705 2 times, resulting in a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
The remainder is 123 after subtracting 1582 from 1705.
Include the next digit (0) from the dividend after 123, then repeat: 1230 / 791

Going ahead to step 7:
1230 divided by 791 is 1 with a remainder of 439.
Record the quotient 1 as the next digit in the result. 
Result so far: 3621.0
If we subtract 791 from 1230, we get 439.
Take the next digit (7) from the dividend and append it to 439, then repeat: 4397 / 791

On to step 8:
791 goes into 4397 5 times with a remainder of 442.
The next digit of our result is 5. 
Result so far: 36215.0
The remainder is 442 after subtracting 3955 from 4397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 9:
791 can be fit into 4420 5 times, resulting in a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 36215.5
Subtracting 3955 from 4420 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 10:
791 can be fit into 4650 5 times, resulting in a remainder of 695.
Use 5 as the next digit of our solution. 
Result so far: 36215.55
Subtracting 3955 from 4650 leaves us with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

The final outcome is 36215.55, with a leftover of 0.695.
