Let's divide 507909 by 8
We're looking to find how many times 8 goes into 507909.

Step 1:
The number 8 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 8

On to step 2:
When dividing 50 by 8, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 48 from 50 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 8

On to step 3:
If we divide 27 by 8, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 24 from 27 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 8

Let's proceed to step 4:
8 goes into 39 4 times with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 634.0
If we take 32 away from 39, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 8

Let's proceed to step 5:
8 can be fit into 70 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 6348.0
Subtracting 64 from 70 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 8

Step 6:
69 divided by 8 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 63488.0
Deduct 64 from 69 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.

Moving on to step 7:
8 can be fit into 50 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 63488.6
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 63488.62
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.

Moving on to step 9:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 63488.625
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.

Let's proceed to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 63488.625
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.

Moving on to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 63488.625
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.

Our division results in 63488.625 with a remaining 0.0.
