2557930 ÷ 797 
The aim is to understand the frequency of 797 in 2557930.

On to step 1:
797 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 797

Step 2:
The number 797 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 797

On to step 3:
When dividing 255 by 797, we get 0 with a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 255 and we're left with 255.
Bring next digit (7) of the dividend behind the 255 and repeat the process: 2557 / 797

Moving on to step 4:
The number 797 fits into 2557 3 times, leaving a remainder of 166.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2391 from 2557, we get 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 797

Step 5:
797 goes into 1669 2 times with a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 1594 from 1669 to get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 797

Moving on to step 6:
797 goes into 753 0 times with a remainder of 753.
The next digit of our result is 0. 
Result so far: 320.0
Subtracting 0 from 753 leaves us with 753.
Append the next digit (0) from the dividend to 753 and continue with: 7530 / 797

Let's proceed to step 7:
The number 797 fits into 7530 9 times, leaving a remainder of 357.
The next digit of our result is 9. 
Result so far: 3209.0
If we subtract 7173 from 7530, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 8:
3570 divided by 797 is 4 with a remainder of 382.
The number 4 becomes the next digit in our result. 
Result so far: 3209.4
If we take 3188 away from 3570, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 9:
797 goes into 3820 4 times with a remainder of 632.
The next digit of our result is 4. 
Result so far: 3209.44
If we take 3188 away from 3820, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final result is 3209.44 with a remainder of 0.632.
