30342915 ÷ 306 
We want to figure out the number of times 30342915 can be divided by 306.

Let's proceed to step 1:
When dividing 3 by 306, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 306

On to step 2:
The number 306 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.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 306

Going ahead to step 3:
306 goes into 303 0 times with a remainder of 303.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Fetch the next digit (4) from the dividend, attach it to 303 and continue: 3034 / 306

Advancing to step 4:
The number 306 fits into 3034 9 times, leaving a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 2754 from 3034, we get 280.
Append the next digit (2) from the dividend to 280 and continue with: 2802 / 306

Advancing to step 5:
If we divide 2802 by 306, we get 9 and a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 2754 from 2802 to get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 306

Step 6:
306 can be fit into 489 1 times, resulting in a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 991.0
If we subtract 306 from 489, we get 183.
Take the next digit (1) from the dividend and append it to 183, then repeat: 1831 / 306

Step 7:
306 goes into 1831 5 times with a remainder of 301.
Use 5 as the next digit of our solution. 
Result so far: 9915.0
If we subtract 1530 from 1831, we get 301.
Fetch the next digit (5) from the dividend, attach it to 301 and continue: 3015 / 306

Let's proceed to step 8:
306 goes into 3015 9 times with a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 99159.0
If we take 2754 away from 3015, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 9:
When dividing 2610 by 306, we get 8 with a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 99159.8
The remainder is 162 after subtracting 2448 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 10:
306 goes into 1620 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 99159.85
If we take 1530 away from 1620, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
The number 306 fits into 900 2 times, leaving a remainder of 288.
The next digit of our result is 2. 
Result so far: 99159.852
If we take 612 away from 900, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 12:
306 can be fit into 2880 9 times, resulting in a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 99159.8529
If we take 2754 away from 2880, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
If we divide 1260 by 306, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 99159.85294
If we subtract 1224 from 1260, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
The number 306 fits into 360 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 99159.852941
Subtract 306 from 360 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
306 can be fit into 540 1 times, resulting in a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 99159.8529411
The remainder is 234 after subtracting 306 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

In conclusion, the division gives 99159.8529411 with a balance of 2.34e-06.
