We look at the division of 209712 by 3 
Let's see how many times 3 fits into 209712.

Let's proceed to step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 2:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 2 after subtracting 18 from 20.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Step 3:
When dividing 29 by 3, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 27 away from 29, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Let's proceed to step 4:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 699.0
The remainder is 0 after subtracting 27 from 27.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Moving on to step 5:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 6990.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

On to step 6:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 69904.0
Deduct 12 from 12 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 69904.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 69904.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 69904.0 and a remainder of 0.0.
