Let's divide 688443 by 63
The aim is to understand the frequency of 63 in 688443.

On to step 1:
63 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 63

Step 2:
When dividing 68 by 63, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 63 from 68 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 63

On to step 3:
The number 63 fits into 58 0 times, leaving a remainder of 58.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 58, we get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 63

Step 4:
63 goes into 584 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we subtract 567 from 584, we get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 63

Let's proceed to step 5:
If we divide 174 by 63, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 1092.0
Subtract 126 from 174 to get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 63

Advancing to step 6:
483 divided by 63 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 10927.0
If we take 441 away from 483, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
63 goes into 420 6 times with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 10927.6
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
63 can be fit into 420 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 10927.66
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 10927.66 with a balance of 0.042.
