We're dividing 580423 by 80 
We want to figure out the number of times 580423 can be divided by 80.

Let's proceed to step 1:
5 divided by 80 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 80

Advancing to step 2:
80 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 80

Let's proceed to step 3:
If we divide 580 by 80, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 560 from 580, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 80

Going ahead to step 4:
80 can be fit into 204 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 160 from 204 to get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 80

Advancing to step 5:
80 goes into 442 5 times with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 725.0
Subtract 400 from 442 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 80

On to step 6:
The number 80 fits into 423 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 7255.0
Deduct 400 from 423 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
80 can be fit into 230 2 times, resulting in a remainder of 70.
The next digit of our result is 2. 
Result so far: 7255.2
If we take 160 away from 230, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 7255.28
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7255.287
If we take 560 away from 600, we end up 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.

Let's proceed to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7255.2875
If we subtract 400 from 400, 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.

Going ahead to step 11:
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: 7255.2875
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7255.2875
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 7255.2875, and the remainder is 0.0.
