We look at the division of 72623908 by 568 
The aim is to understand the frequency of 568 in 72623908.

Going ahead to step 1:
The number 568 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 568

Moving on to step 2:
When dividing 72 by 568, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 568

Advancing to step 3:
If we divide 726 by 568, we get 1 and a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 568 from 726 leaves us with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 568

Let's proceed to step 4:
When dividing 1582 by 568, we get 2 with a remainder of 446.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 446 after subtracting 1136 from 1582.
Grab the next digit (3) from the dividend, add it to 446, then carry on: 4463 / 568

On to step 5:
568 goes into 4463 7 times with a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we take 3976 away from 4463, we end up with 487.
Grab the next digit (9) from the dividend, add it to 487, then carry on: 4879 / 568

Let's proceed to step 6:
4879 divided by 568 is 8 with a remainder of 335.
Record the quotient 8 as the next digit in the result. 
Result so far: 1278.0
Subtracting 4544 from 4879 leaves us with 335.
Grab the next digit (0) from the dividend, add it to 335, then carry on: 3350 / 568

Step 7:
When dividing 3350 by 568, we get 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 12785.0
The remainder is 510 after subtracting 2840 from 3350.
Include the next digit (8) from the dividend after 510, then repeat: 5108 / 568

Going ahead to step 8:
5108 divided by 568 is 8 with a remainder of 564.
Use 8 as the next digit of our solution. 
Result so far: 127858.0
Subtract 4544 from 5108 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 9:
568 goes into 5640 9 times with a remainder of 528.
Write down 9 as next digit of the result. 
Result so far: 127858.9
The remainder is 528 after subtracting 5112 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 10:
568 goes into 5280 9 times with a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 127858.99
If we subtract 5112 from 5280, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 127858.99 with a remainder of 0.168.
