Let's divide 63423839 by 668
The aim is to understand the frequency of 668 in 63423839.

Let's proceed to step 1:
668 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 668

Moving on to step 2:
If we divide 63 by 668, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 668

Let's proceed to step 3:
If we divide 634 by 668, we get 0 and a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 634, we get 634.
Bring next digit (2) of the dividend behind the 634 and repeat the process: 6342 / 668

Advancing to step 4:
If we divide 6342 by 668, we get 9 and a remainder of 330.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6012 from 6342, we get 330.
Append the next digit (3) from the dividend to 330 and continue with: 3303 / 668

Going ahead to step 5:
The number 668 fits into 3303 4 times, leaving a remainder of 631.
The next digit of our result is 4. 
Result so far: 94.0
If we take 2672 away from 3303, we end up with 631.
Include the next digit (8) from the dividend after 631, then repeat: 6318 / 668

Advancing to step 6:
668 can be fit into 6318 9 times, resulting in a remainder of 306.
Write down 9 as next digit of the result. 
Result so far: 949.0
Subtracting 6012 from 6318 leaves us with 306.
Grab the next digit (3) from the dividend, add it to 306, then carry on: 3063 / 668

Step 7:
If we divide 3063 by 668, we get 4 and a remainder of 391.
The next digit of our result is 4. 
Result so far: 9494.0
Subtracting 2672 from 3063 leaves us with 391.
Include the next digit (9) from the dividend after 391, then repeat: 3919 / 668

Advancing to step 8:
668 goes into 3919 5 times with a remainder of 579.
Write down 5 as next digit of the result. 
Result so far: 94945.0
If we subtract 3340 from 3919, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 9:
5790 divided by 668 is 8 with a remainder of 446.
The next digit of our result is 8. 
Result so far: 94945.8
The remainder is 446 after subtracting 5344 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 10:
668 goes into 4460 6 times with a remainder of 452.
Record the quotient 6 as the next digit in the result. 
Result so far: 94945.86
If we take 4008 away from 4460, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 11:
The number 668 fits into 4520 6 times, leaving a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 94945.866
Subtracting 4008 from 4520 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 94945.866 and a remainder of 0.0512.
