We're dividing 30437281 by 15 
We want to figure out the number of times 30437281 can be divided by 15.

On to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 15

Moving on to step 2:
If we divide 30 by 15, we get 2 and 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.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 15

Advancing to step 3:
If we divide 4 by 15, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Moving on to step 4:
43 divided by 15 is 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 202.0
The remainder is 13 after subtracting 30 from 43.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 15

Step 5:
15 can be fit into 137 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 2029.0
The remainder is 2 after subtracting 135 from 137.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 15

Advancing to step 6:
When dividing 22 by 15, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 20291.0
The remainder is 7 after subtracting 15 from 22.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

On to step 7:
15 can be fit into 78 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 202915.0
Deduct 75 from 78 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Moving on to step 8:
When dividing 31 by 15, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2029152.0
The remainder is 1 after subtracting 30 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2029152.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 2029152.06
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 2029152.066
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 2029152.066 and a remainder of 0.001.
