We look at the division of 309091 by 9 
Our goal is to divide 309091 by 9.

Let's proceed to step 1:
If we divide 3 by 9, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Step 2:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 27 away from 30, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 9

Moving on to step 3:
The number 9 fits into 39 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 36 away from 39, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 9

Advancing to step 4:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 343.0
If we take 27 away from 30, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 9

On to step 5:
9 goes into 39 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 3434.0
If we subtract 36 from 39, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 9

On to step 6:
9 can be fit into 31 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 34343.0
Deduct 27 from 31 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
9 goes into 40 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34343.4
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 34343.44
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 34343.44 with a balance of 0.004.
