We divide 580658 by 9
Let's see how many times 9 fits into 580658.

Step 1:
9 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 9

Step 2:
58 divided by 9 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 54 from 58 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 9

Let's proceed to step 3:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 36 from 40 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 9

On to step 4:
When dividing 46 by 9, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
Subtracting 45 from 46 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 9

On to step 5:
If we divide 15 by 9, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 6451.0
Deduct 9 from 15 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 9

Let's proceed to step 6:
9 goes into 68 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 64517.0
If we subtract 63 from 68, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 64517.5
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
9 goes into 50 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 64517.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 64517.55 and a remainder of 0.005.
