We're dividing 810245 by 5 
Let's see how many times 5 fits into 810245.

On to step 1:
5 goes into 8 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 5 from 8, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 5

Let's proceed to step 2:
5 can be fit into 31 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 30 from 31 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 5

Moving on to step 3:
The number 5 fits into 10 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 162.0
If we subtract 10 from 10, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 5

Advancing to step 4:
If we divide 2 by 5, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1620.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 5

Going ahead to step 5:
24 divided by 5 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 16204.0
The remainder is 4 after subtracting 20 from 24.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 5

Step 6:
45 divided by 5 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 162049.0
Subtracting 45 from 45 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.

Let's proceed to step 7:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 162049.0
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.

Moving on to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 162049.0
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.

Our division results in 162049.0 with a remaining 0.0.
