Let's divide 402409 by 63
The aim is to understand the frequency of 63 in 402409.

Let's proceed to step 1:
When dividing 4 by 63, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 63

Let's proceed to step 2:
The number 63 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 63

Moving on to step 3:
The number 63 fits into 402 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 378 from 402, we get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 63

Going ahead to step 4:
63 can be fit into 244 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 189 from 244 to get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 63

Advancing to step 5:
63 goes into 550 8 times with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 638.0
Subtracting 504 from 550 leaves us with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 63

Going ahead to step 6:
The number 63 fits into 469 7 times, leaving a remainder of 28.
The next digit of our result is 7. 
Result so far: 6387.0
The remainder is 28 after subtracting 441 from 469.
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 7:
63 can be fit into 280 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 6387.4
Subtract 252 from 280 to 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 8:
280 divided by 63 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 6387.44
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.

The final outcome is 6387.44, with a leftover of 0.028.
