78822140 divided by 515 
We want to divide 78822140 by 515.

Step 1:
The number 515 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 515

Advancing to step 2:
515 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 515

Going ahead to step 3:
515 can be fit into 788 1 times, resulting in a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 515 from 788 leaves us with 273.
Include the next digit (2) from the dividend after 273, then repeat: 2732 / 515

Step 4:
515 goes into 2732 5 times with a remainder of 157.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2575 from 2732 and we're left with 157.
Append the next digit (2) from the dividend to 157 and continue with: 1572 / 515

Advancing to step 5:
The number 515 fits into 1572 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we take 1545 away from 1572, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 515

Moving on to step 6:
515 goes into 271 0 times with a remainder of 271.
Use 0 as the next digit of our solution. 
Result so far: 1530.0
Subtracting 0 from 271 leaves us with 271.
Include the next digit (4) from the dividend after 271, then repeat: 2714 / 515

Let's proceed to step 7:
2714 divided by 515 is 5 with a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 15305.0
If we take 2575 away from 2714, we end up with 139.
Take the next digit (0) from the dividend and append it to 139, then repeat: 1390 / 515

Let's proceed to step 8:
515 can be fit into 1390 2 times, resulting in a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 153052.0
Deduct 1030 from 1390 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 9:
3600 divided by 515 is 6 with a remainder of 510.
Record the quotient 6 as the next digit in the result. 
Result so far: 153052.6
The remainder is 510 after subtracting 3090 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
5100 divided by 515 is 9 with a remainder of 465.
Put 9 as the next digit of the answer. 
Result so far: 153052.69
If we take 4635 away from 5100, we end up with 465.
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:
4650 divided by 515 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 153052.699
The remainder is 15 after subtracting 4635 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 153052.699 and a remainder of 0.0015.
