We look at the division of 78946491 by 563 
The aim is to understand the frequency of 563 in 78946491.

Going ahead to step 1:
If we divide 7 by 563, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 563

Step 2:
563 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 563

Step 3:
If we divide 789 by 563, we get 1 and a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 563 from 789, we get 226.
Bring next digit (4) of the dividend behind the 226 and repeat the process: 2264 / 563

Step 4:
The number 563 fits into 2264 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 12 after subtracting 2252 from 2264.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 563

Going ahead to step 5:
563 goes into 126 0 times with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 140.0
The remainder is 126 after subtracting 0 from 126.
Fetch the next digit (4) from the dividend, attach it to 126 and continue: 1264 / 563

Let's proceed to step 6:
563 goes into 1264 2 times with a remainder of 138.
The next digit of our result is 2. 
Result so far: 1402.0
The remainder is 138 after subtracting 1126 from 1264.
Include the next digit (9) from the dividend after 138, then repeat: 1389 / 563

Step 7:
The number 563 fits into 1389 2 times, leaving a remainder of 263.
Use 2 as the next digit of our solution. 
Result so far: 14022.0
If we subtract 1126 from 1389, we get 263.
Take the next digit (1) from the dividend and append it to 263, then repeat: 2631 / 563

Let's proceed to step 8:
When dividing 2631 by 563, we get 4 with a remainder of 379.
Use 4 as the next digit of our solution. 
Result so far: 140224.0
If we take 2252 away from 2631, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 9:
563 can be fit into 3790 6 times, resulting in a remainder of 412.
Use 6 as the next digit of our solution. 
Result so far: 140224.6
Deduct 3378 from 3790 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 10:
563 goes into 4120 7 times with a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 140224.67
Subtract 3941 from 4120 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 11:
563 goes into 1790 3 times with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 140224.673
If we subtract 1689 from 1790, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 12:
If we divide 1010 by 563, we get 1 and a remainder of 447.
Put 1 as the next digit of the answer. 
Result so far: 140224.6731
If we take 563 away from 1010, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 13:
563 can be fit into 4470 7 times, resulting in a remainder of 529.
Write down 7 as next digit of the result. 
Result so far: 140224.67317
If we subtract 3941 from 4470, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Let's proceed to step 14:
563 can be fit into 5290 9 times, resulting in a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 140224.673179
Deduct 5067 from 5290 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 15:
When dividing 2230 by 563, we get 3 with a remainder of 541.
The next digit of our result is 3. 
Result so far: 140224.6731793
If we subtract 1689 from 2230, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 16:
563 goes into 5410 9 times with a remainder of 343.
Put 9 as the next digit of the answer. 
Result so far: 140224.67317939
If we take 5067 away from 5410, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final outcome is 140224.67317939, with a leftover of 3.43e-07.
