We look at the division of 478345 by 63 
The aim is to understand the frequency of 63 in 478345.

Step 1:
63 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 63

Let's proceed to step 2:
47 divided by 63 is 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 63

Step 3:
If we divide 478 by 63, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 441 from 478 leaves us with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 63

Moving on to step 4:
63 goes into 373 5 times with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 315 from 373 leaves us with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 63

Advancing to step 5:
When dividing 584 by 63, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 759.0
Subtracting 567 from 584 leaves us with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 63

On to step 6:
When dividing 175 by 63, we get 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 7592.0
If we subtract 126 from 175, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
63 can be fit into 490 7 times, resulting in a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 7592.7
Subtracting 441 from 490 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
If we divide 490 by 63, we get 7 and a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 7592.77
The remainder is 49 after subtracting 441 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 7592.77, with a leftover of 0.049.
