We look at the division of 553463 by 63 
The aim is to understand the frequency of 63 in 553463.

Advancing to step 1:
If we divide 5 by 63, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 63

Going ahead to step 2:
63 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 63

Let's proceed to step 3:
63 can be fit into 553 8 times, resulting in a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 504 from 553 and we're left with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 63

Let's proceed to step 4:
494 divided by 63 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 441 from 494 to get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 63

Going ahead to step 5:
When dividing 536 by 63, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
Subtracting 504 from 536 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 63

Let's proceed to step 6:
323 divided by 63 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 8785.0
Subtracting 315 from 323 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 63, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 8785.1
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
The number 63 fits into 170 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 8785.12
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
440 divided by 63 is 6 with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 8785.126
The remainder is 62 after subtracting 378 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
63 can be fit into 620 9 times, resulting in a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 8785.1269
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
530 divided by 63 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8785.12698
The remainder is 26 after subtracting 504 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
63 goes into 260 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8785.126984
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
If we divide 80 by 63, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 8785.1269841
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
63 can be fit into 170 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 8785.12698412
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8785.12698412 with a remainder of 4.4e-08.
