578740 divided by 8 
We're looking to find how many times 8 goes into 578740.

On to step 1:
8 can be fit into 5 0 times, resulting in 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.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 8

Going ahead to step 2:
8 can be fit into 57 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 56 from 57, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 8

On to step 3:
18 divided by 8 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 16 from 18 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 8

Step 4:
8 goes into 27 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 723.0
The remainder is 3 after subtracting 24 from 27.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 8

Advancing to step 5:
The number 8 fits into 34 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7234.0
Deduct 32 from 34 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 8

Let's proceed to step 6:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 72342.0
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 72342.5
Subtracting 40 from 40 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.

Going ahead to step 8:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 72342.5
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.

Step 9:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72342.5
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.

After the division, we end up with 72342.5 and a remainder of 0.0.
