We're dividing 309073 by 99 
Let's see how many times 99 fits into 309073.

Going ahead to step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 99

On to step 2:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 99

Moving on to step 3:
When dividing 309 by 99, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 297 from 309 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 99

Let's proceed to step 4:
120 divided by 99 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 21 after subtracting 99 from 120.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 99

Advancing to step 5:
99 goes into 217 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
Deduct 198 from 217 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 99

Advancing to step 6:
99 goes into 193 1 times with a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 3121.0
Subtract 99 from 193 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 7:
The number 99 fits into 940 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 3121.9
If we subtract 891 from 940, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
When dividing 490 by 99, we get 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3121.94
Subtracting 396 from 490 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
99 can be fit into 940 9 times, resulting in a remainder of 49.
The next digit of our result is 9. 
Result so far: 3121.949
The remainder is 49 after subtracting 891 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
When dividing 490 by 99, we get 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 3121.9494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
940 divided by 99 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 3121.94949
Subtract 891 from 940 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
490 divided by 99 is 4 with a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 3121.949494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 13:
99 goes into 940 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 3121.9494949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
99 goes into 490 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 3121.94949494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 3121.94949494 with a balance of 9.4e-08.
