We divide 583449 by 80
Let's see how many times 80 fits into 583449.

Advancing 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
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 80

Step 2:
58 divided by 80 is 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 80

Step 3:
80 goes into 583 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 560 from 583 and we're left with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 80

Step 4:
The number 80 fits into 234 2 times, leaving a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 74 after subtracting 160 from 234.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 80

On to step 5:
80 goes into 744 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 729.0
The remainder is 24 after subtracting 720 from 744.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 80

Step 6:
249 divided by 80 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 7293.0
Subtract 240 from 249 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 80 fits into 90 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 7293.1
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 7293.11
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7293.11 with a remainder of 0.02.
