We're dividing 408673 by 8 
We're looking to find how many times 8 goes into 408673.

Advancing to step 1:
8 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 8

Advancing to step 2:
When dividing 40 by 8, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 40 from 40 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 8

Moving on to step 3:
8 divided by 8 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 8 from 8 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 8

Moving on to step 4:
6 divided by 8 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 8

Let's proceed to step 5:
If we divide 67 by 8, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 5108.0
If we subtract 64 from 67, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 8

Moving on to step 6:
8 goes into 33 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 51084.0
If we subtract 32 from 33, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 8, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 51084.1
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 8, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 51084.12
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.

Step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 51084.125
If we take 40 away from 40, 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 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: 51084.125
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.

Moving on to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51084.125
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.

The final result is 51084.125 with a remainder of 0.0.
