We look at the division of 654942 by 63 
The aim is to understand the frequency of 63 in 654942.

Step 1:
6 divided by 63 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 63

Step 2:
63 can be fit into 65 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 63 from 65.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 63

On to step 3:
24 divided by 63 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 24, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 63

Advancing to step 4:
The number 63 fits into 249 3 times, leaving a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 189 from 249, we get 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 63

Advancing to step 5:
When dividing 604 by 63, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
If we take 567 away from 604, we end up with 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 63

On to step 6:
When dividing 372 by 63, we get 5 with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 10395.0
Subtracting 315 from 372 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
63 can be fit into 570 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 10395.9
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 63 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10395.9
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
63 goes into 300 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10395.904
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
The number 63 fits into 480 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 10395.9047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
If we divide 390 by 63, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10395.90476
If we take 378 away from 390, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 63 is 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 10395.904761
If we take 63 away from 120, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 13:
63 goes into 570 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 10395.9047619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
63 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10395.9047619
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 10395.9047619, with a leftover of 3e-08.
