We're dividing 596442 by 63 
The aim is to understand the frequency of 63 in 596442.

On to step 1:
If we divide 5 by 63, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 63

Moving on to step 2:
63 can be fit into 59 0 times, resulting in a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 63

Advancing to step 3:
When dividing 596 by 63, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 29 after subtracting 567 from 596.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 63

Let's proceed to step 4:
When dividing 294 by 63, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 252 away from 294, we end up with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 63

Going ahead to step 5:
The number 63 fits into 424 6 times, leaving a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 946.0
If we take 378 away from 424, we end up with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 63

Moving on to step 6:
63 goes into 462 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 9467.0
If we subtract 441 from 462, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 63, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 9467.3
The remainder is 21 after subtracting 189 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
63 goes into 210 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 9467.33
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 9467.33, with a leftover of 0.021.
