51237916 divided by 515 
We want to divide 51237916 by 515.

Let's proceed to step 1:
When dividing 5 by 515, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 515

On to step 2:
515 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 515

Going ahead to step 3:
When dividing 512 by 515, we get 0 with a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 512 to get 512.
Append the next digit (3) from the dividend to 512 and continue with: 5123 / 515

Step 4:
When dividing 5123 by 515, we get 9 with a remainder of 488.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 4635 away from 5123, we end up with 488.
Bring next digit (7) of the dividend behind the 488 and repeat the process: 4887 / 515

On to step 5:
4887 divided by 515 is 9 with a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 99.0
The remainder is 252 after subtracting 4635 from 4887.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 515

Step 6:
If we divide 2529 by 515, we get 4 and a remainder of 469.
Put 4 as the next digit of the answer. 
Result so far: 994.0
Subtract 2060 from 2529 to get 469.
Grab the next digit (1) from the dividend, add it to 469, then carry on: 4691 / 515

Moving on to step 7:
If we divide 4691 by 515, we get 9 and a remainder of 56.
The next digit of our result is 9. 
Result so far: 9949.0
Subtract 4635 from 4691 to get 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 515

On to step 8:
If we divide 566 by 515, we get 1 and a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 99491.0
Subtract 515 from 566 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 515, we get 0 and a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 99491.0
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
515 can be fit into 5100 9 times, resulting in a remainder of 465.
Write down 9 as next digit of the result. 
Result so far: 99491.09
The remainder is 465 after subtracting 4635 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 11:
515 goes into 4650 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 99491.099
If we take 4635 away from 4650, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 99491.099 with a remainder of 0.0015.
