9 divided by 3 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Advancing to step 2:
3 goes into 9 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 9 away from 9, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Step 3:
The number 3 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Advancing to step 4:
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: 3309.0
Subtract 27 from 29 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

On to step 5:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 33099.0
If we take 27 away from 28, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Let's proceed to step 6:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 330996.0
If we subtract 18 from 19, we 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.

Advancing to step 7:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 330996.3
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.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 330996.33
Subtracting 9 from 10 leaves us 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.
