580517 divided by 72 
We want to figure out the number of times 580517 can be divided by 72.

On to step 1:
72 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
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 / 72

On to step 2:
If we divide 58 by 72, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 72

On to step 3:
When dividing 580 by 72, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 576 from 580 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 72

Step 4:
45 divided by 72 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 45, we get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 72

Moving on to step 5:
If we divide 451 by 72, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 806.0
If we take 432 away from 451, we end up with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 72

Moving on to step 6:
When dividing 197 by 72, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 8062.0
Deduct 144 from 197 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
72 can be fit into 530 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 8062.7
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
When dividing 260 by 72, we get 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 8062.73
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
72 goes into 440 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8062.736
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
72 goes into 80 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 8062.7361
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 8062.73611
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 8062.73611 with a remaining 8e-06.
