We look at the division of 73600172 by 563 
The aim is to understand the frequency of 563 in 73600172.

Let's proceed to step 1:
The number 563 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 563

On to step 2:
The number 563 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 563

Let's proceed to step 3:
The number 563 fits into 736 1 times, leaving a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 563 from 736 and we're left with 173.
Include the next digit (0) from the dividend after 173, then repeat: 1730 / 563

Moving on to step 4:
563 can be fit into 1730 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1689 from 1730 to get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 563

On to step 5:
When dividing 410 by 563, we get 0 with a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 410 to get 410.
Bring next digit (1) of the dividend behind the 410 and repeat the process: 4101 / 563

Advancing to step 6:
The number 563 fits into 4101 7 times, leaving a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 1307.0
Deduct 3941 from 4101 and we're left with 160.
Take the next digit (7) from the dividend and append it to 160, then repeat: 1607 / 563

Going ahead to step 7:
The number 563 fits into 1607 2 times, leaving a remainder of 481.
Use 2 as the next digit of our solution. 
Result so far: 13072.0
If we take 1126 away from 1607, we end up with 481.
Grab the next digit (2) from the dividend, add it to 481, then carry on: 4812 / 563

Let's proceed to step 8:
When dividing 4812 by 563, we get 8 with a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 130728.0
Subtract 4504 from 4812 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
The number 563 fits into 3080 5 times, leaving a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 130728.5
Deduct 2815 from 3080 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 10:
The number 563 fits into 2650 4 times, leaving a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 130728.54
Subtracting 2252 from 2650 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
563 goes into 3980 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 130728.547
The remainder is 39 after subtracting 3941 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
When dividing 390 by 563, we get 0 with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 130728.547
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
3900 divided by 563 is 6 with a remainder of 522.
Write down 6 as next digit of the result. 
Result so far: 130728.54706
Subtract 3378 from 3900 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 14:
5220 divided by 563 is 9 with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 130728.547069
Deduct 5067 from 5220 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 15:
563 goes into 1530 2 times with a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 130728.5470692
The remainder is 404 after subtracting 1126 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 16:
4040 divided by 563 is 7 with a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 130728.54706927
If we subtract 3941 from 4040, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final result is 130728.54706927 with a remainder of 9.9e-08.
