We look at the division of 80455 by 10 
We want to divide 80455 by 10.

Going ahead to step 1:
10 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 10

On to step 2:
If we divide 80 by 10, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 80 from 80 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 10

Going ahead to step 3:
10 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 10

Moving on to step 4:
If we divide 45 by 10, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 804.0
Subtracting 40 from 45 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 10

Step 5:
10 goes into 55 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8045.0
Subtract 50 from 55 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.

Advancing to step 6:
50 divided by 10 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8045.5
Subtract 50 from 50 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.

Advancing to step 7:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8045.5
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.

Step 8:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8045.5
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.

After the division, we end up with 8045.5 and a remainder of 0.0.
