We divide 30429668 by 15
We want to divide 30429668 by 15.

On to step 1:
The number 15 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
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 15

Let's proceed to step 2:
15 can be fit into 30 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 30 from 30.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

Moving on to step 3:
The number 15 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 15

Let's proceed to step 4:
15 can be fit into 42 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 202.0
Subtracting 30 from 42 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 15

On to step 5:
The number 15 fits into 129 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 2028.0
Subtracting 120 from 129 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 15

Let's proceed to step 6:
15 can be fit into 96 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 20286.0
Deduct 90 from 96 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Advancing to step 7:
66 divided by 15 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 202864.0
The remainder is 6 after subtracting 60 from 66.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

Step 8:
15 can be fit into 68 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 2028644.0
Subtract 60 from 68 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2028644.5
Deduct 75 from 80 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 2028644.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2028644.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 2028644.533 with a remaining 0.0005.
