We're dividing 580720 by 4 
We want to divide 580720 by 4.

Step 1:
If we divide 5 by 4, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

On to step 2:
If we divide 18 by 4, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 16 from 18 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Going ahead to step 3:
When dividing 20 by 4, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 145.0
If we take 20 away from 20, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

Going ahead to step 4:
7 divided by 4 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1451.0
Subtracting 4 from 7 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Step 5:
32 divided by 4 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 14518.0
If we take 32 away from 32, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 4

Let's proceed to step 6:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 145180.0
Subtract 0 from 0 to 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.

Advancing to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 145180.0
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.

Let's proceed to step 8:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 145180.0
Deduct 0 from 0 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.

The final result is 145180.0 with a remainder of 0.0.
