We look at the division of 285117 by 63 
The aim is to understand the frequency of 63 in 285117.

Moving on to step 1:
63 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 63

Step 2:
28 divided by 63 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 63

Step 3:
The number 63 fits into 285 4 times, leaving a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 252 from 285 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 63

On 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: 45.0
The remainder is 16 after subtracting 315 from 331.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 63

Going ahead to step 5:
When dividing 161 by 63, we get 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 452.0
Deduct 126 from 161 and we're left with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 63

Advancing to step 6:
When dividing 357 by 63, we get 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 4525.0
Subtract 315 from 357 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
If we divide 420 by 63, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4525.6
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
420 divided by 63 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4525.66
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 4525.66 with a remainder of 0.042.
