We divide 640120 by 96
The aim is to understand the frequency of 96 in 640120.

Let's proceed to step 1:
96 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 96

Moving on to step 2:
The number 96 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 96

Moving on to step 3:
The number 96 fits into 640 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 576 from 640 and we're left with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 96

Advancing to step 4:
641 divided by 96 is 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we subtract 576 from 641, we get 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 96

Moving on to step 5:
96 goes into 652 6 times with a remainder of 76.
The next digit of our result is 6. 
Result so far: 666.0
If we take 576 away from 652, we end up with 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 96

On to step 6:
The number 96 fits into 760 7 times, leaving a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 6667.0
If we subtract 672 from 760, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 7:
96 goes into 880 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 6667.9
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
96 goes into 160 1 times with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 6667.91
The remainder is 64 after subtracting 96 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
96 goes into 640 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 6667.916
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 96 fits into 640 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 6667.9166
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 6667.9166 and a remainder of 0.00064.
