459888 ÷ 80 
The aim is to understand the frequency of 80 in 459888.

Let's proceed to step 1:
4 divided by 80 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 80

Advancing to step 2:
The number 80 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 80

Going ahead to step 3:
If we divide 459 by 80, we get 5 and a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 400 from 459 leaves us with 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 80

Advancing to step 4:
When dividing 598 by 80, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 560 from 598 to get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 80

Moving on to step 5:
If we divide 388 by 80, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 574.0
If we subtract 320 from 388, we get 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 80

On to step 6:
80 can be fit into 688 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5748.0
If we subtract 640 from 688, 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.

Let's proceed to step 7:
The number 80 fits into 480 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 5748.6
Deduct 480 from 480 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.

Moving on to step 8:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5748.6
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5748.6
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.

The final result is 5748.6 with a remainder of 0.0.
