We divide 323309 by 31
We want to figure out the number of times 323309 can be divided by 31.

Advancing to step 1:
31 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 31

On to step 2:
If we divide 32 by 31, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 31 from 32, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 31

Going ahead to step 3:
13 divided by 31 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 13, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 31

Let's proceed to step 4:
133 divided by 31 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 9 after subtracting 124 from 133.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 31

Going ahead to step 5:
90 divided by 31 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1042.0
If we take 62 away from 90, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 31

Advancing to step 6:
31 goes into 289 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 10429.0
Deduct 279 from 289 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 10429.3
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 10429.32
The remainder is 8 after subtracting 62 from 70.
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 9:
31 goes into 80 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 10429.322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 10429.322 and a remainder of 0.0018.
