We look at the division of 222159 by 63 
The aim is to understand the frequency of 63 in 222159.

Let's proceed to step 1:
If we divide 2 by 63, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 63

Moving on to step 2:
When dividing 22 by 63, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 63

Going ahead to step 3:
63 can be fit into 222 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 33 after subtracting 189 from 222.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 63

Let's proceed to step 4:
The number 63 fits into 331 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 315 from 331 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 63

Moving on to step 5:
When dividing 165 by 63, we get 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 352.0
If we take 126 away from 165, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 63

Step 6:
399 divided by 63 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 3526.0
Deduct 378 from 399 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 63, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3526.3
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
63 goes into 210 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 3526.33
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 3526.33, with a leftover of 0.021.
