We look at the division of 30686 by 9 
We want to divide 30686 by 9.

Going ahead to step 1:
When dividing 3 by 9, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Advancing to step 2:
When dividing 30 by 9, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 27 from 30 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 9

Advancing to step 3:
9 can be fit into 36 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 36 from 36 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 9

Let's proceed to step 4:
9 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 340.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 9

Moving on to step 5:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 3409.0
If we subtract 81 from 86, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3409.5
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3409.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 3409.55 with a remaining 0.005.
