We're dividing 20461 by 63 
The aim is to understand the frequency of 63 in 20461.

Advancing to step 1:
63 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 63

Moving on to step 2:
20 divided by 63 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 63

Let's proceed to step 3:
When dividing 204 by 63, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 189 from 204 to get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 63

Step 4:
The number 63 fits into 156 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 126 from 156 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 63

On to step 5:
If we divide 301 by 63, we get 4 and a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
If we subtract 252 from 301, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 6:
490 divided by 63 is 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 324.7
Deduct 441 from 490 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
63 goes into 490 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 324.77
The remainder is 49 after subtracting 441 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 324.77 with a remaining 0.049.
