30289561 ÷ 515 
Our goal is to divide 30289561 by 515.

Going ahead to step 1:
515 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 515

Advancing to step 2:
If we divide 30 by 515, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 515

Let's proceed to step 3:
If we divide 302 by 515, we get 0 and a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 302 and we're left with 302.
Include the next digit (8) from the dividend after 302, then repeat: 3028 / 515

Let's proceed to step 4:
If we divide 3028 by 515, we get 5 and a remainder of 453.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 2575 from 3028 to get 453.
Include the next digit (9) from the dividend after 453, then repeat: 4539 / 515

Let's proceed to step 5:
515 can be fit into 4539 8 times, resulting in a remainder of 419.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 4120 away from 4539, we end up with 419.
Include the next digit (5) from the dividend after 419, then repeat: 4195 / 515

Step 6:
When dividing 4195 by 515, we get 8 with a remainder of 75.
The next digit of our result is 8. 
Result so far: 588.0
If we take 4120 away from 4195, we end up with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 515

Moving on to step 7:
When dividing 756 by 515, we get 1 with a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 5881.0
Subtracting 515 from 756 leaves us with 241.
Bring next digit (1) of the dividend behind the 241 and repeat the process: 2411 / 515

Moving on to step 8:
515 can be fit into 2411 4 times, resulting in a remainder of 351.
The number 4 becomes the next digit in our result. 
Result so far: 58814.0
Deduct 2060 from 2411 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 9:
515 goes into 3510 6 times with a remainder of 420.
The next digit of our result is 6. 
Result so far: 58814.6
Subtract 3090 from 3510 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 10:
4200 divided by 515 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 58814.68
Subtract 4120 from 4200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 515, we get 1 with a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 58814.681
Subtract 515 from 800 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 12:
515 goes into 2850 5 times with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 58814.6815
Subtract 2575 from 2850 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 13:
2750 divided by 515 is 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 58814.68155
The remainder is 175 after subtracting 2575 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 58814.68155 with a remainder of 0.000175.
