We look at the division of 49408869 by 568 
The aim is to understand the frequency of 568 in 49408869.

Advancing to step 1:
The number 568 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 568

Let's proceed to step 2:
The number 568 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 568

On to step 3:
568 goes into 494 0 times with a remainder of 494.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 494 leaves us with 494.
Bring next digit (0) of the dividend behind the 494 and repeat the process: 4940 / 568

Advancing to step 4:
568 goes into 4940 8 times with a remainder of 396.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 4544 from 4940 leaves us with 396.
Append the next digit (8) from the dividend to 396 and continue with: 3968 / 568

Advancing to step 5:
568 can be fit into 3968 6 times, resulting in a remainder of 560.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 3408 from 3968 to get 560.
Fetch the next digit (8) from the dividend, attach it to 560 and continue: 5608 / 568

Moving on to step 6:
568 can be fit into 5608 9 times, resulting in a remainder of 496.
The next digit of our result is 9. 
Result so far: 869.0
If we take 5112 away from 5608, we end up with 496.
Include the next digit (6) from the dividend after 496, then repeat: 4966 / 568

Step 7:
568 can be fit into 4966 8 times, resulting in a remainder of 422.
Put 8 as the next digit of the answer. 
Result so far: 8698.0
Subtract 4544 from 4966 to get 422.
Fetch the next digit (9) from the dividend, attach it to 422 and continue: 4229 / 568

Step 8:
568 goes into 4229 7 times with a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 86987.0
Subtracting 3976 from 4229 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
2530 divided by 568 is 4 with a remainder of 258.
The next digit of our result is 4. 
Result so far: 86987.4
Subtracting 2272 from 2530 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 10:
2580 divided by 568 is 4 with a remainder of 308.
Write down 4 as next digit of the result. 
Result so far: 86987.44
Deduct 2272 from 2580 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Our division results in 86987.44 with a remaining 0.308.
