We look at the division of 408863 by 8 
We're looking to find how many times 8 goes into 408863.

Advancing to step 1:
If we divide 4 by 8, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 8

Going ahead to step 2:
When dividing 40 by 8, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 40 from 40, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 8

Step 3:
The number 8 fits into 8 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 8

Going ahead to step 4:
8 goes into 8 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 511.0
If we take 8 away from 8, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 8

On to step 5:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 5110.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 8

Step 6:
The number 8 fits into 63 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 51107.0
Subtracting 56 from 63 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 51107.8
The remainder is 6 after subtracting 64 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 8 fits into 60 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 51107.87
Subtract 56 from 60 to get 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:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 51107.875
The remainder is 0 after subtracting 40 from 40.
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 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51107.875
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 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51107.875
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 51107.875 with a remaining 0.0.
