We look at the division of 450623 by 8 
Let's see how many times 8 fits into 450623.

Step 1:
8 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 8

Going ahead to step 2:
If we divide 45 by 8, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 5 after subtracting 40 from 45.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 8

Advancing to step 3:
If we divide 50 by 8, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 48 from 50 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 8

Going ahead to step 4:
8 can be fit into 26 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 563.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 8

Advancing to step 5:
The number 8 fits into 22 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 5632.0
Subtracting 16 from 22 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 8

Step 6:
When dividing 63 by 8, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 56327.0
The remainder is 7 after subtracting 56 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
8 goes into 70 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 56327.8
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 56327.87
If we subtract 56 from 60, we 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.
Put 5 as the next digit of the answer. 
Result so far: 56327.875
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.

On to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 56327.875
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.

On to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56327.875
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.

The final result is 56327.875 with a remainder of 0.0.
