We look at the division of 307390 by 99 
Our goal is to divide 307390 by 99.

Step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 99

Moving on to step 2:
30 divided by 99 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 99

Going ahead to step 3:
If we divide 307 by 99, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 10 after subtracting 297 from 307.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 99

Advancing to step 4:
When dividing 103 by 99, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 99 from 103 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 99

Advancing to step 5:
99 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 49 and we're left with 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 99

Let's proceed to step 6:
If we divide 490 by 99, we get 4 and a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 3104.0
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.

Step 7:
When dividing 940 by 99, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 3104.9
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.

Let's proceed to step 8:
If we divide 490 by 99, we get 4 and a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 3104.94
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.

Moving on to step 9:
99 can be fit into 940 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 3104.949
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.

Advancing to step 10:
99 can be fit into 490 4 times, resulting in a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 3104.9494
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.

Going ahead to step 11:
99 goes into 940 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 3104.94949
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 12:
The number 99 fits into 490 4 times, leaving a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 3104.949494
The remainder is 94 after subtracting 396 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 13:
If we divide 940 by 99, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 3104.9494949
Subtracting 891 from 940 leaves us 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.

Moving on to step 14:
490 divided by 99 is 4 with a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 3104.94949494
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.

The final outcome is 3104.94949494, with a leftover of 9.4e-08.
