408688 divided by 80 
Our goal is to divide 408688 by 80.

Step 1:
80 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 80

Advancing to step 2:
40 divided by 80 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 80

Going ahead to step 3:
If we divide 408 by 80, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 400 from 408 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

On to step 4:
80 can be fit into 86 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 80 from 86, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 80

Let's proceed to step 5:
68 divided by 80 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 510.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 80

Moving on to step 6:
80 can be fit into 688 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 5108.0
The remainder is 48 after subtracting 640 from 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
When dividing 480 by 80, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 5108.6
If we take 480 away from 480, 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 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 5108.6
Deduct 0 from 0 and we're left 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.

On to step 9:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5108.6
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.

After the division, we end up with 5108.6 and a remainder of 0.0.
