We look at the division of 223155 by 63 
The aim is to understand the frequency of 63 in 223155.

On to step 1:
If we divide 2 by 63, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 63

Going ahead to step 2:
63 goes into 22 0 times with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 63

Moving on to step 3:
If we divide 223 by 63, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 3.0
If we take 189 away from 223, we end up with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 63

Advancing to step 4:
When dividing 341 by 63, we get 5 with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 26 after subtracting 315 from 341.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 63

Going ahead to step 5:
63 goes into 265 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 354.0
Subtracting 252 from 265 leaves us with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 63

Step 6:
63 goes into 135 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 3542.0
Subtract 126 from 135 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 63, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 3542.1
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
63 goes into 270 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 3542.14
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 63, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 3542.142
Deduct 126 from 180 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
When dividing 540 by 63, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 3542.1428
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 63 fits into 360 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 3542.14285
Deduct 315 from 360 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
The number 63 fits into 450 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 3542.142857
Subtract 441 from 450 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
63 can be fit into 90 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 3542.1428571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
The number 63 fits into 270 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 3542.14285714
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 3542.14285714 with a remainder of 1.8e-08.
