51180431 ÷ 517 
We want to divide 51180431 by 517.

Advancing to step 1:
If we divide 5 by 517, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 517

Let's proceed to step 2:
The number 517 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 517

Going ahead to step 3:
517 can be fit into 511 0 times, resulting in a remainder of 511.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Fetch the next digit (8) from the dividend, attach it to 511 and continue: 5118 / 517

Going ahead to step 4:
517 goes into 5118 9 times with a remainder of 465.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 4653 away from 5118, we end up with 465.
Bring next digit (0) of the dividend behind the 465 and repeat the process: 4650 / 517

Going ahead to step 5:
517 can be fit into 4650 8 times, resulting in a remainder of 514.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 4136 from 4650 to get 514.
Bring next digit (4) of the dividend behind the 514 and repeat the process: 5144 / 517

On to step 6:
The number 517 fits into 5144 9 times, leaving a remainder of 491.
Put 9 as the next digit of the answer. 
Result so far: 989.0
The remainder is 491 after subtracting 4653 from 5144.
Bring next digit (3) of the dividend behind the 491 and repeat the process: 4913 / 517

Advancing to step 7:
The number 517 fits into 4913 9 times, leaving a remainder of 260.
The next digit of our result is 9. 
Result so far: 9899.0
The remainder is 260 after subtracting 4653 from 4913.
Include the next digit (1) from the dividend after 260, then repeat: 2601 / 517

Advancing to step 8:
517 can be fit into 2601 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 98995.0
Deduct 2585 from 2601 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
517 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 98995.0
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
If we divide 1600 by 517, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 98995.03
Subtract 1551 from 1600 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 11:
490 divided by 517 is 0 with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 98995.03
Subtract 0 from 490 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 12:
517 can be fit into 4900 9 times, resulting in a remainder of 247.
Use 9 as the next digit of our solution. 
Result so far: 98995.0309
Subtracting 4653 from 4900 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 13:
517 goes into 2470 4 times with a remainder of 402.
Use 4 as the next digit of our solution. 
Result so far: 98995.03094
The remainder is 402 after subtracting 2068 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 14:
517 goes into 4020 7 times with a remainder of 401.
The number 7 becomes the next digit in our result. 
Result so far: 98995.030947
If we take 3619 away from 4020, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 15:
4010 divided by 517 is 7 with a remainder of 391.
Use 7 as the next digit of our solution. 
Result so far: 98995.0309477
The remainder is 391 after subtracting 3619 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The final outcome is 98995.0309477, with a leftover of 3.91e-06.
