668775 divided by 63 
The aim is to understand the frequency of 63 in 668775.

On to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 63

Going ahead to step 2:
66 divided by 63 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 63 from 66, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 63

Advancing to step 3:
When dividing 38 by 63, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 38, we get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 63

Step 4:
If we divide 387 by 63, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtracting 378 from 387 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 63

Advancing to step 5:
63 goes into 97 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1061.0
The remainder is 34 after subtracting 63 from 97.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 63

Moving on to step 6:
345 divided by 63 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10615.0
If we subtract 315 from 345, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
63 can be fit into 300 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 10615.4
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 63 fits into 480 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 10615.47
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 63, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10615.476
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
63 goes into 120 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 10615.4761
The remainder is 57 after subtracting 63 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
63 goes into 570 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 10615.47619
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
63 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10615.47619
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 63 fits into 300 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10615.4761904
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
63 can be fit into 480 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 10615.47619047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 10615.47619047 and a remainder of 3.9e-08.
