Let's divide 511009 by 3
We want to figure out the number of times 511009 can be divided by 3.

Advancing to step 1:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Let's proceed to step 2:
3 goes into 21 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 21 from 21, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 170.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Going ahead to step 4:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1703.0
Subtracting 9 from 10 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Advancing to step 5:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 17033.0
Subtracting 9 from 10 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

On to step 6:
If we divide 19 by 3, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 170336.0
If we take 18 away from 19, we end up 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.

Step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 170336.3
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.

On to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 170336.33
If we take 9 away from 10, we end up 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.

In conclusion, the division gives 170336.33 with a balance of 0.001.
