We look at the division of 37556243 by 563 
The aim is to understand the frequency of 563 in 37556243.

Step 1:
563 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 563

Step 2:
563 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 563

Advancing to step 3:
563 goes into 375 0 times with a remainder of 375.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 375 after subtracting 0 from 375.
Include the next digit (5) from the dividend after 375, then repeat: 3755 / 563

On to step 4:
563 goes into 3755 6 times with a remainder of 377.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 3378 from 3755 leaves us with 377.
Bring next digit (6) of the dividend behind the 377 and repeat the process: 3776 / 563

Moving on to step 5:
563 goes into 3776 6 times with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 3378 from 3776, we get 398.
Take the next digit (2) from the dividend and append it to 398, then repeat: 3982 / 563

On to step 6:
The number 563 fits into 3982 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 667.0
Subtracting 3941 from 3982 leaves us with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 563

Let's proceed to step 7:
The number 563 fits into 414 0 times, leaving a remainder of 414.
The number 0 becomes the next digit in our result. 
Result so far: 6670.0
Deduct 0 from 414 and we're left with 414.
Take the next digit (3) from the dividend and append it to 414, then repeat: 4143 / 563

Let's proceed to step 8:
When dividing 4143 by 563, we get 7 with a remainder of 202.
Use 7 as the next digit of our solution. 
Result so far: 66707.0
The remainder is 202 after subtracting 3941 from 4143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 9:
2020 divided by 563 is 3 with a remainder of 331.
The next digit of our result is 3. 
Result so far: 66707.3
Subtract 1689 from 2020 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 10:
563 goes into 3310 5 times with a remainder of 495.
The number 5 becomes the next digit in our result. 
Result so far: 66707.35
The remainder is 495 after subtracting 2815 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 11:
4950 divided by 563 is 8 with a remainder of 446.
Write down 8 as next digit of the result. 
Result so far: 66707.358
If we subtract 4504 from 4950, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 12:
4460 divided by 563 is 7 with a remainder of 519.
Use 7 as the next digit of our solution. 
Result so far: 66707.3587
If we take 3941 away from 4460, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 13:
563 can be fit into 5190 9 times, resulting in a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 66707.35879
Deduct 5067 from 5190 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 14:
563 goes into 1230 2 times with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 66707.358792
If we subtract 1126 from 1230, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 15:
1040 divided by 563 is 1 with a remainder of 477.
Use 1 as the next digit of our solution. 
Result so far: 66707.3587921
Subtract 563 from 1040 to get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 16:
4770 divided by 563 is 8 with a remainder of 266.
Record the quotient 8 as the next digit in the result. 
Result so far: 66707.35879218
If we take 4504 away from 4770, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

In conclusion, the division gives 66707.35879218 with a balance of 2.66e-07.
