Let's divide 80340976 by 563
The aim is to understand the frequency of 563 in 80340976.

Advancing to step 1:
If we divide 8 by 563, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 563

Let's proceed to step 2:
80 divided by 563 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 563

On to step 3:
563 goes into 803 1 times with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 563 from 803 to get 240.
Fetch the next digit (4) from the dividend, attach it to 240 and continue: 2404 / 563

Step 4:
If we divide 2404 by 563, we get 4 and a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2252 from 2404 leaves us with 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 563

Going ahead to step 5:
563 goes into 1520 2 times with a remainder of 394.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
The remainder is 394 after subtracting 1126 from 1520.
Bring next digit (9) of the dividend behind the 394 and repeat the process: 3949 / 563

Step 6:
563 can be fit into 3949 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1427.0
Subtract 3941 from 3949 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 563

Moving on to step 7:
563 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 14270.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 563

Advancing to step 8:
563 can be fit into 876 1 times, resulting in a remainder of 313.
The next digit of our result is 1. 
Result so far: 142701.0
The remainder is 313 after subtracting 563 from 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 9:
The number 563 fits into 3130 5 times, leaving a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 142701.5
If we subtract 2815 from 3130, we get 315.
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:
The number 563 fits into 3150 5 times, leaving a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 142701.55
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.

The final outcome is 142701.55, with a leftover of 0.335.
