We look at the division of 18679527 by 563 
The aim is to understand the frequency of 563 in 18679527.

Step 1:
When dividing 1 by 563, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 563

Advancing to step 2:
The number 563 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 563

Advancing to step 3:
The number 563 fits into 186 0 times, leaving a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 186 after subtracting 0 from 186.
Grab the next digit (7) from the dividend, add it to 186, then carry on: 1867 / 563

Advancing to step 4:
1867 divided by 563 is 3 with a remainder of 178.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1689 from 1867 leaves us with 178.
Take the next digit (9) from the dividend and append it to 178, then repeat: 1789 / 563

Going ahead to step 5:
563 can be fit into 1789 3 times, resulting in a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 1689 from 1789 leaves us with 100.
Append the next digit (5) from the dividend to 100 and continue with: 1005 / 563

On to step 6:
The number 563 fits into 1005 1 times, leaving a remainder of 442.
Write down 1 as next digit of the result. 
Result so far: 331.0
The remainder is 442 after subtracting 563 from 1005.
Bring next digit (2) of the dividend behind the 442 and repeat the process: 4422 / 563

Step 7:
The number 563 fits into 4422 7 times, leaving a remainder of 481.
The next digit of our result is 7. 
Result so far: 3317.0
Deduct 3941 from 4422 and we're left with 481.
Bring next digit (7) of the dividend behind the 481 and repeat the process: 4817 / 563

Moving on to step 8:
563 goes into 4817 8 times with a remainder of 313.
The next digit of our result is 8. 
Result so far: 33178.0
The remainder is 313 after subtracting 4504 from 4817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
563 goes into 3130 5 times with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 33178.5
The remainder is 315 after subtracting 2815 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 10:
563 can be fit into 3150 5 times, resulting in a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 33178.55
Deduct 2815 from 3150 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Our division results in 33178.55 with a remaining 0.335.
