We're dividing 477209 by 3 
We want to figure out the number of times 477209 can be divided by 3.

On to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Advancing to step 2:
The number 3 fits into 17 5 times, leaving a remainder of 2.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 15 from 17 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

Step 3:
27 divided by 3 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 159.0
The remainder is 0 after subtracting 27 from 27.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Going ahead to step 4:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1590.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Moving on to step 5:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 15906.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Step 6:
The number 3 fits into 29 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 159069.0
If we take 27 away from 29, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 159069.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 159069.66
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.

The final result is 159069.66 with a remainder of 0.002.
