We're dividing 25176051 by 515 
Let's see how many times 515 fits into 25176051.

On to step 1:
When dividing 2 by 515, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 515

Step 2:
515 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 515

On to step 3:
251 divided by 515 is 0 with a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Take the next digit (7) from the dividend and append it to 251, then repeat: 2517 / 515

On to step 4:
The number 515 fits into 2517 4 times, leaving a remainder of 457.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2060 from 2517 leaves us with 457.
Take the next digit (6) from the dividend and append it to 457, then repeat: 4576 / 515

Going ahead to step 5:
515 goes into 4576 8 times with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 4120 from 4576 to get 456.
Fetch the next digit (0) from the dividend, attach it to 456 and continue: 4560 / 515

Moving on to step 6:
4560 divided by 515 is 8 with a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 488.0
Deduct 4120 from 4560 and we're left with 440.
Grab the next digit (5) from the dividend, add it to 440, then carry on: 4405 / 515

Step 7:
515 goes into 4405 8 times with a remainder of 285.
Put 8 as the next digit of the answer. 
Result so far: 4888.0
Deduct 4120 from 4405 and we're left with 285.
Include the next digit (1) from the dividend after 285, then repeat: 2851 / 515

Advancing to step 8:
515 can be fit into 2851 5 times, resulting in a remainder of 276.
Put 5 as the next digit of the answer. 
Result so far: 48885.0
The remainder is 276 after subtracting 2575 from 2851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 9:
2760 divided by 515 is 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 48885.5
The remainder is 185 after subtracting 2575 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 10:
The number 515 fits into 1850 3 times, leaving a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 48885.53
Deduct 1545 from 1850 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 11:
The number 515 fits into 3050 5 times, leaving a remainder of 475.
The next digit of our result is 5. 
Result so far: 48885.535
Subtract 2575 from 3050 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 12:
When dividing 4750 by 515, we get 9 with a remainder of 115.
The next digit of our result is 9. 
Result so far: 48885.5359
If we subtract 4635 from 4750, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
1150 divided by 515 is 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 48885.53592
If we take 1030 away from 1150, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
515 goes into 1200 2 times with a remainder of 170.
The next digit of our result is 2. 
Result so far: 48885.535922
Subtract 1030 from 1200 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

After the division, we end up with 48885.535922 and a remainder of 1.7e-05.
