We're dividing 821648 by 10 
Let's see how many times 10 fits into 821648.

On to step 1:
The number 10 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 10

Let's proceed to step 2:
82 divided by 10 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 80 from 82, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

On to step 3:
If we divide 21 by 10, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 1 after subtracting 20 from 21.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 10

Let's proceed to step 4:
16 divided by 10 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 821.0
Subtract 10 from 16 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 10

Let's proceed to step 5:
10 can be fit into 64 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 8216.0
Subtract 60 from 64 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 10

Moving on to step 6:
10 can be fit into 48 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 82164.0
Deduct 40 from 48 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
10 goes into 80 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 82164.8
If we take 80 away from 80, 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 8:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 82164.8
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.

Going ahead to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 82164.8
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.

The final result is 82164.8 with a remainder of 0.0.
