454820 ÷ 8 
We're looking to find how many times 8 goes into 454820.

Step 1:
8 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 8

Advancing to step 2:
45 divided by 8 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 40 from 45 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 8

Let's proceed to step 3:
8 can be fit into 54 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 48 from 54 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 8

Moving on to step 4:
68 divided by 8 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
If we take 64 away from 68, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 8

On to step 5:
42 divided by 8 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5685.0
The remainder is 2 after subtracting 40 from 42.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

On to step 6:
20 divided by 8 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 56852.0
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.

Moving on to step 7:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 56852.5
Subtracting 40 from 40 leaves us 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.

Going ahead to step 8:
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: 56852.5
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.

On to step 9:
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: 56852.5
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.

Our division results in 56852.5 with a remaining 0.0.
