Let's proceed to step 4:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2146.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Step 5:
When dividing 24 by 3, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 21468.0
The remainder is 0 after subtracting 24 from 24.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Let's proceed to step 6:
5 divided by 3 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 214681.0
If we take 3 away from 5, 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.

Moving on to step 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 214681.6
Subtracting 18 from 20 leaves us 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 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 214681.66
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.
