We look at the division of 128830 by 63 
The aim is to understand the frequency of 63 in 128830.

Advancing to step 1:
1 divided by 63 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 63

Step 2:
63 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 63

On to step 3:
63 goes into 128 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 126 from 128, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 63

Let's proceed to step 4:
When dividing 28 by 63, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 28, we get 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 63

Step 5:
When dividing 283 by 63, we get 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 204.0
The remainder is 31 after subtracting 252 from 283.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 63

On to step 6:
The number 63 fits into 310 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 2044.0
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
The number 63 fits into 580 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 2044.9
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 63 fits into 130 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2044.92
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 63 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 2044.92
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
63 can be fit into 400 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 2044.9206
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
63 goes into 220 3 times with a remainder of 31.
The next digit of our result is 3. 
Result so far: 2044.92063
If we take 189 away from 220, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 2044.920634
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
580 divided by 63 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 2044.9206349
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
When dividing 130 by 63, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2044.92063492
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 2044.92063492, with a leftover of 4e-09.
