We divide 585728 by 80
The aim is to understand the frequency of 80 in 585728.

Going ahead to step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 80

Step 2:
80 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 80

Let's proceed to step 3:
If we divide 585 by 80, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 560 from 585 to get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 80

Let's proceed to step 4:
80 goes into 257 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 240 away from 257, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 80

Let's proceed to step 5:
80 goes into 172 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 732.0
Subtract 160 from 172 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 80

Let's proceed to step 6:
80 can be fit into 128 1 times, resulting in a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 7321.0
Subtract 80 from 128 to 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.

Advancing to step 7:
If we divide 480 by 80, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 7321.6
Subtracting 480 from 480 leaves us 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.

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: 7321.6
Subtracting 0 from 0 leaves us 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 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7321.6
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 quotient of the division is 7321.6, and the remainder is 0.0.
