408557 divided by 8 
We want to divide 408557 by 8.

Step 1:
When dividing 4 by 8, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 8

On 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
Subtracting 40 from 40 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 8

Step 3:
8 divided by 8 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 8

Let's proceed to step 4:
If we divide 5 by 8, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 510.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 8

Let's proceed to step 5:
When dividing 55 by 8, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 5106.0
If we take 48 away from 55, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 8

Step 6:
If we divide 77 by 8, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 51069.0
Subtract 72 from 77 to 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.

Moving on to step 7:
8 can be fit into 50 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 51069.6
If we take 48 away from 50, we end up with 2.
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:
20 divided by 8 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 51069.62
If we take 16 away from 20, we end up 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.
Put 5 as the next digit of the answer. 
Result so far: 51069.625
Subtract 40 from 40 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.

Let's proceed to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51069.625
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.

Advancing to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51069.625
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.

The final outcome is 51069.625, with a leftover of 0.0.
