Let's divide 823421 by 9
We want to divide 823421 by 9.

Going ahead to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 9

Advancing to step 2:
82 divided by 9 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 1 after subtracting 81 from 82.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 9

Advancing to step 3:
13 divided by 9 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 9 from 13, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 9

On to step 4:
When dividing 44 by 9, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 914.0
If we take 36 away from 44, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 9

Step 5:
82 divided by 9 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9149.0
If we subtract 81 from 82, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 9

Let's proceed to step 6:
11 divided by 9 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 91491.0
The remainder is 2 after subtracting 9 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 91491.2
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
9 goes into 20 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 91491.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 91491.22 with a remaining 0.002.
