We look at the division of 8861816 by 568 
The aim is to understand the frequency of 568 in 8861816.

Going ahead to step 1:
568 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 568

Advancing to step 2:
When dividing 88 by 568, we get 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 568

On to step 3:
When dividing 886 by 568, we get 1 with a remainder of 318.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 568 from 886 leaves us with 318.
Grab the next digit (1) from the dividend, add it to 318, then carry on: 3181 / 568

Step 4:
568 can be fit into 3181 5 times, resulting in a remainder of 341.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2840 from 3181 and we're left with 341.
Include the next digit (8) from the dividend after 341, then repeat: 3418 / 568

On to step 5:
568 goes into 3418 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Deduct 3408 from 3418 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 568

Let's proceed to step 6:
568 goes into 101 0 times with a remainder of 101.
The number 0 becomes the next digit in our result. 
Result so far: 1560.0
Subtracting 0 from 101 leaves us with 101.
Grab the next digit (6) from the dividend, add it to 101, then carry on: 1016 / 568

Moving on to step 7:
568 goes into 1016 1 times with a remainder of 448.
Put 1 as the next digit of the answer. 
Result so far: 15601.0
Deduct 568 from 1016 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 8:
568 can be fit into 4480 7 times, resulting in a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 15601.7
Subtracting 3976 from 4480 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 9:
568 goes into 5040 8 times with a remainder of 496.
Put 8 as the next digit of the answer. 
Result so far: 15601.78
The remainder is 496 after subtracting 4544 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 10:
When dividing 4960 by 568, we get 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 15601.788
Subtracting 4544 from 4960 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 15601.788, and the remainder is 0.0416.
