We look at the division of 81285 by 5 
We want to divide 81285 by 5.

Step 1:
8 divided by 5 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 8 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 5

Advancing to step 2:
If we divide 31 by 5, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 30 from 31, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 5

On to step 3:
12 divided by 5 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we take 10 away from 12, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 5

Step 4:
If we divide 28 by 5, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 1625.0
The remainder is 3 after subtracting 25 from 28.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 5

Advancing to step 5:
If we divide 35 by 5, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 16257.0
If we subtract 35 from 35, 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.

Step 6:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16257.0
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.

Let's proceed to step 7:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16257.0
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 16257.0 with a remaining 0.0.
