Let's divide 998671 by 63
The aim is to understand the frequency of 63 in 998671.

Step 1:
If we divide 9 by 63, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 63

On to step 2:
63 goes into 99 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 63 away from 99, we end up with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 63

Let's proceed to step 3:
368 divided by 63 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 315 from 368 and we're left with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 63

Going ahead to step 4:
63 can be fit into 536 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Subtracting 504 from 536 leaves us with 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 63

On to step 5:
63 can be fit into 327 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 1585.0
Deduct 315 from 327 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 63

Moving on to step 6:
The number 63 fits into 121 1 times, leaving a remainder of 58.
The next digit of our result is 1. 
Result so far: 15851.0
If we take 63 away from 121, we end up 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.

Moving on to step 7:
When dividing 580 by 63, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 15851.9
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
63 goes into 130 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 15851.92
If we take 126 away from 130, we end up 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.

Moving on to step 9:
If we divide 40 by 63, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15851.92
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
63 goes into 400 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 15851.9206
If we subtract 378 from 400, we get 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:
The number 63 fits into 220 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 15851.92063
The remainder is 31 after subtracting 189 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 15851.920634
If we take 252 away from 310, we end up 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:
The number 63 fits into 580 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 15851.9206349
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
63 goes into 130 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 15851.92063492
Subtract 126 from 130 to 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.

In conclusion, the division gives 15851.92063492 with a balance of 4e-09.
