75439 divided by 63 
The aim is to understand the frequency of 63 in 75439.

Advancing to step 1:
7 divided by 63 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 63

Advancing to step 2:
75 divided by 63 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 63 away from 75, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 63

Moving on to step 3:
The number 63 fits into 124 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 61 after subtracting 63 from 124.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 63

Advancing to step 4:
When dividing 613 by 63, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we subtract 567 from 613, we get 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 63

Going ahead to step 5:
If we divide 469 by 63, we get 7 and a remainder of 28.
The next digit of our result is 7. 
Result so far: 1197.0
If we subtract 441 from 469, we get 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 6:
63 can be fit into 280 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1197.4
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 63 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1197.44
Deduct 252 from 280 and we're left 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.

Our division results in 1197.44 with a remaining 0.028.
