We're dividing 639715 by 96 
The aim is to understand the frequency of 96 in 639715.

On to step 1:
When dividing 6 by 96, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 96

Step 2:
When dividing 63 by 96, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 96

Going ahead to step 3:
The number 96 fits into 639 6 times, leaving a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 576 from 639 and we're left with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 96

Advancing to step 4:
When dividing 637 by 96, we get 6 with a remainder of 61.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 576 from 637, we get 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 96

Going ahead to step 5:
If we divide 611 by 96, we get 6 and a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
If we take 576 away from 611, we end up with 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 96

On to step 6:
96 goes into 355 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 6663.0
Deduct 288 from 355 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
96 can be fit into 670 6 times, resulting in a remainder of 94.
Record the quotient 6 as the next digit in the result. 
Result so far: 6663.6
If we take 576 away from 670, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 8:
The number 96 fits into 940 9 times, leaving a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 6663.69
Subtracting 864 from 940 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
96 goes into 760 7 times with a remainder of 88.
Use 7 as the next digit of our solution. 
Result so far: 6663.697
Subtracting 672 from 760 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
If we divide 880 by 96, we get 9 and a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 6663.6979
Deduct 864 from 880 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 96, we get 1 and a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 6663.69791
If we take 96 away from 160, we end up 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 12:
640 divided by 96 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 6663.697916
If we take 576 away from 640, we end up 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.

On to step 13:
If we divide 640 by 96, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 6663.6979166
The remainder is 64 after subtracting 576 from 640.
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 6663.6979166 and a remainder of 6.4e-07.
