We look at the division of 13785 by 63 
The aim is to understand the frequency of 63 in 13785.

Advancing to step 1:
The number 63 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 63

Moving on to step 2:
13 divided by 63 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 63

Step 3:
63 can be fit into 137 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 126 from 137 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 63

Let's proceed to step 4:
The number 63 fits into 118 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 63 from 118, we get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 63

On to step 5:
If we divide 555 by 63, we get 8 and a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
Subtracting 504 from 555 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 6:
63 can be fit into 510 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 218.8
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 63 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 218.8
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
If we divide 600 by 63, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 218.809
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
330 divided by 63 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 218.8095
The remainder is 15 after subtracting 315 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
63 can be fit into 150 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 218.80952
Subtracting 126 from 150 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 218.809523
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
The number 63 fits into 510 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 218.8095238
The remainder is 6 after subtracting 504 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
63 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 218.8095238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 218.8095238 with a remainder of 6e-08.
