We look at the division of 571676 by 63 
The aim is to understand the frequency of 63 in 571676.

Step 1:
If we divide 5 by 63, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 63

Advancing to step 2:
The number 63 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 63

Advancing to step 3:
If we divide 571 by 63, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 567 from 571 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 63

Moving on to step 4:
63 goes into 46 0 times with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we subtract 0 from 46, we get 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 63

Step 5:
When dividing 467 by 63, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 907.0
Deduct 441 from 467 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 63

On to step 6:
The number 63 fits into 266 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 9074.0
The remainder is 14 after subtracting 252 from 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 63, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 9074.2
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 63 fits into 140 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 9074.22
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 9074.22 and a remainder of 0.014.
