641640 ÷ 96 
The aim is to understand the frequency of 96 in 641640.

Step 1:
96 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 subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 96

Going ahead to step 2:
96 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 96

Going ahead to step 3:
641 divided by 96 is 6 with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 576 from 641, we get 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 96

Let's proceed to step 4:
When dividing 656 by 96, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 576 from 656, we get 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 96

Moving on to step 5:
If we divide 804 by 96, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 668.0
If we take 768 away from 804, we end up with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 96

Going ahead to step 6:
When dividing 360 by 96, we get 3 with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 6683.0
Deduct 288 from 360 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
When dividing 720 by 96, we get 7 with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 6683.7
If we subtract 672 from 720, we get 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 96 fits into 480 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6683.75
If we subtract 480 from 480, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 96, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6683.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
96 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6683.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6683.75, with a leftover of 0.0.
