We're dividing 320512 by 3 
We're looking to find how many times 3 goes into 320512.

Moving on to step 1:
3 divided by 3 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Moving on to step 2:
2 divided by 3 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Step 3:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 106.0
If we take 18 away from 20, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Step 4:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1068.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Let's proceed to step 5:
11 divided by 3 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 10683.0
If we take 9 away from 11, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Moving on to step 6:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 106837.0
Subtract 21 from 22 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 106837.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 106837.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 106837.33 with a remaining 0.001.
