Let's divide 21520 by 96
The aim is to understand the frequency of 96 in 21520.

Advancing to step 1:
96 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 96

Going ahead to step 2:
If we divide 21 by 96, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 96

Going ahead to step 3:
The number 96 fits into 215 2 times, leaving a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 192 from 215 and we're left with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 96

Advancing to step 4:
When dividing 232 by 96, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 40 after subtracting 192 from 232.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 96

Let's proceed to step 5:
96 can be fit into 400 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 224.0
Deduct 384 from 400 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.

On to step 6:
96 can be fit into 160 1 times, resulting in a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 224.1
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.

Let's proceed to step 7:
If we divide 640 by 96, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 224.16
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
The number 96 fits into 640 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 224.166
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 224.166 and a remainder of 0.0064.
