We divide 21354980 by 563
The aim is to understand the frequency of 563 in 21354980.

Step 1:
2 divided by 563 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 563

Step 2:
563 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 563

Advancing to step 3:
The number 563 fits into 213 0 times, leaving a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Grab the next digit (5) from the dividend, add it to 213, then carry on: 2135 / 563

Advancing to step 4:
If we divide 2135 by 563, we get 3 and a remainder of 446.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 446 after subtracting 1689 from 2135.
Include the next digit (4) from the dividend after 446, then repeat: 4464 / 563

On to step 5:
563 goes into 4464 7 times with a remainder of 523.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 3941 from 4464 and we're left with 523.
Fetch the next digit (9) from the dividend, attach it to 523 and continue: 5239 / 563

Going ahead to step 6:
5239 divided by 563 is 9 with a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 379.0
If we take 5067 away from 5239, we end up with 172.
Fetch the next digit (8) from the dividend, attach it to 172 and continue: 1728 / 563

Advancing to step 7:
1728 divided by 563 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 3793.0
The remainder is 39 after subtracting 1689 from 1728.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 563

Let's proceed to step 8:
563 goes into 390 0 times with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 37930.0
Subtract 0 from 390 to get 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 9:
563 can be fit into 3900 6 times, resulting in a remainder of 522.
Record the quotient 6 as the next digit in the result. 
Result so far: 37930.6
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 10:
If we divide 5220 by 563, we get 9 and a remainder of 153.
Record the quotient 9 as the next digit in the result. 
Result so far: 37930.69
Subtract 5067 from 5220 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 11:
563 can be fit into 1530 2 times, resulting in a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 37930.692
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.

Let's proceed to step 12:
563 goes into 4040 7 times with a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 37930.6927
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.

Moving on to step 13:
When dividing 990 by 563, we get 1 with a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 37930.69271
Subtract 563 from 990 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 14:
4270 divided by 563 is 7 with a remainder of 329.
The number 7 becomes the next digit in our result. 
Result so far: 37930.692717
Subtracting 3941 from 4270 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 15:
563 can be fit into 3290 5 times, resulting in a remainder of 475.
The next digit of our result is 5. 
Result so far: 37930.6927175
Deduct 2815 from 3290 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 16:
563 goes into 4750 8 times with a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 37930.69271758
If we take 4504 away from 4750, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Our division results in 37930.69271758 with a remaining 2.46e-07.
