963802 ÷ 63 
The aim is to understand the frequency of 63 in 963802.

Advancing to step 1:
9 divided by 63 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 63

Let's proceed to step 2:
63 goes into 96 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 63 from 96, we get 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 63

Let's proceed to step 3:
The number 63 fits into 333 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 18 after subtracting 315 from 333.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 63

Step 4:
63 goes into 188 2 times with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we subtract 126 from 188, we get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 63

Let's proceed to step 5:
620 divided by 63 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 1529.0
Deduct 567 from 620 and we're left with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 63

Step 6:
If we divide 532 by 63, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 15298.0
Subtracting 504 from 532 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
63 goes into 280 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 15298.4
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
When dividing 280 by 63, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 15298.44
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 15298.44, with a leftover of 0.028.
