We're dividing 30290349 by 300 
Our goal is to divide 30290349 by 300.

Moving on to step 1:
3 divided by 300 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 300

Advancing to step 2:
The number 300 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 300

On to step 3:
300 can be fit into 302 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 300 away from 302, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 300

On to step 4:
The number 300 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 300

Advancing to step 5:
If we divide 290 by 300, we get 0 and a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 290 and we're left with 290.
Append the next digit (3) from the dividend to 290 and continue with: 2903 / 300

Moving on to step 6:
300 can be fit into 2903 9 times, resulting in a remainder of 203.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
If we take 2700 away from 2903, we end up with 203.
Bring next digit (4) of the dividend behind the 203 and repeat the process: 2034 / 300

Let's proceed to step 7:
The number 300 fits into 2034 6 times, leaving a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 10096.0
Deduct 1800 from 2034 and we're left with 234.
Take the next digit (9) from the dividend and append it to 234, then repeat: 2349 / 300

On to step 8:
The number 300 fits into 2349 7 times, leaving a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 100967.0
Subtracting 2100 from 2349 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
300 can be fit into 2490 8 times, resulting in a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 100967.8
If we subtract 2400 from 2490, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 300 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 100967.83
Subtracting 900 from 900 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 300 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100967.83
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 300 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 100967.83
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 100967.83 with a balance of 0.0.
