Let's divide 583975 by 80
We want to figure out the number of times 583975 can be divided by 80.

Let's proceed to step 1:
5 divided by 80 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 80

Moving on to step 2:
If we divide 58 by 80, we get 0 and a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 80

Advancing to step 3:
If we divide 583 by 80, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 560 from 583 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 80

Advancing to step 4:
If we divide 239 by 80, we get 2 and a remainder of 79.
The next digit of our result is 2. 
Result so far: 72.0
The remainder is 79 after subtracting 160 from 239.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 80

Moving on to step 5:
If we divide 797 by 80, we get 9 and a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 729.0
If we subtract 720 from 797, we get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 80

On to step 6:
80 can be fit into 775 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 7299.0
If we subtract 720 from 775, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
If we divide 550 by 80, we get 6 and a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 7299.6
The remainder is 70 after subtracting 480 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
700 divided by 80 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 7299.68
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.

Step 9:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7299.687
Subtracting 560 from 600 leaves us 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7299.6875
Subtracting 400 from 400 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.

Step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7299.6875
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7299.6875
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.

After the division, we end up with 7299.6875 and a remainder of 0.0.
