We look at the division of 80323 by 63 
The aim is to understand the frequency of 63 in 80323.

On to step 1:
If we divide 8 by 63, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 63

Advancing to step 2:
80 divided by 63 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 63 from 80 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 63

Moving on to step 3:
The number 63 fits into 173 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 126 away from 173, we end up with 47.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 63

Going ahead to step 4:
63 can be fit into 472 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we subtract 441 from 472, we get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 63

Let's proceed to step 5:
If we divide 313 by 63, we get 4 and a remainder of 61.
The next digit of our result is 4. 
Result so far: 1274.0
Subtract 252 from 313 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 6:
63 goes into 610 9 times with a remainder of 43.
The next digit of our result is 9. 
Result so far: 1274.9
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
63 can be fit into 430 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 1274.96
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
63 can be fit into 520 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1274.968
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 63, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 1274.9682
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
When dividing 340 by 63, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1274.96825
Deduct 315 from 340 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
63 goes into 250 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 1274.968253
Deduct 189 from 250 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
610 divided by 63 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 1274.9682539
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
63 goes into 430 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 1274.96825396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 1274.96825396 and a remainder of 5.2e-08.
