21270 divided by 80 
The aim is to understand the frequency of 80 in 21270.

Moving on to step 1:
The number 80 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 80

Step 2:
The number 80 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 80

Step 3:
The number 80 fits into 212 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 160 from 212 leaves us with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 80

Going ahead to step 4:
The number 80 fits into 527 6 times, leaving a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 480 from 527 to get 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 80

Moving on to step 5:
If we divide 470 by 80, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
If we subtract 400 from 470, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 265.8
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
When dividing 600 by 80, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 265.87
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 265.875
Subtract 400 from 400 to 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.

Moving on to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 265.875
Deduct 0 from 0 and we're left 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.

Advancing to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 265.875
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.

In conclusion, the division gives 265.875 with a balance of 0.0.
