30390915 ÷ 96 
Our goal is to divide 30390915 by 96.

Let's proceed to step 1:
The number 96 fits into 3 0 times, leaving 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 / 96

On to step 2:
96 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 96

Step 3:
The number 96 fits into 303 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 288 from 303 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 96

Advancing to step 4:
159 divided by 96 is 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 96 from 159 and we're left with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 96

Moving on to step 5:
96 goes into 630 6 times with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 316.0
If we take 576 away from 630, we end up with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 96

Moving on to step 6:
96 can be fit into 549 5 times, resulting in a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 3165.0
If we take 480 away from 549, we end up with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 96

Advancing to step 7:
691 divided by 96 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 31657.0
If we subtract 672 from 691, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 96

Step 8:
The number 96 fits into 195 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 316572.0
Deduct 192 from 195 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 96, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 316572.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
96 can be fit into 300 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 316572.03
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 96 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 316572.031
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
96 can be fit into 240 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 316572.0312
Subtracting 192 from 240 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
The number 96 fits into 480 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 316572.03125
Deduct 480 from 480 and we're left 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.

Let's proceed to step 14:
The number 96 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 316572.03125
If we subtract 0 from 0, we 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.

Step 15:
0 divided by 96 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 316572.03125
If we subtract 0 from 0, we 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.

The final result is 316572.03125 with a remainder of 0.0.
