82126077 ÷ 515 
Our goal is to divide 82126077 by 515.

On to step 1:
The number 515 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 515

Advancing to step 2:
If we divide 82 by 515, we get 0 and a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 515

Going ahead to step 3:
515 goes into 821 1 times with a remainder of 306.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 515 away from 821, we end up with 306.
Bring next digit (2) of the dividend behind the 306 and repeat the process: 3062 / 515

On to step 4:
515 goes into 3062 5 times with a remainder of 487.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2575 from 3062 to get 487.
Include the next digit (6) from the dividend after 487, then repeat: 4876 / 515

Moving on to step 5:
515 goes into 4876 9 times with a remainder of 241.
The next digit of our result is 9. 
Result so far: 159.0
The remainder is 241 after subtracting 4635 from 4876.
Fetch the next digit (0) from the dividend, attach it to 241 and continue: 2410 / 515

Moving on to step 6:
If we divide 2410 by 515, we get 4 and a remainder of 350.
The number 4 becomes the next digit in our result. 
Result so far: 1594.0
If we subtract 2060 from 2410, we get 350.
Fetch the next digit (7) from the dividend, attach it to 350 and continue: 3507 / 515

Moving on to step 7:
515 can be fit into 3507 6 times, resulting in a remainder of 417.
Write down 6 as next digit of the result. 
Result so far: 15946.0
Deduct 3090 from 3507 and we're left with 417.
Append the next digit (7) from the dividend to 417 and continue with: 4177 / 515

Step 8:
515 can be fit into 4177 8 times, resulting in a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 159468.0
Subtracting 4120 from 4177 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
515 goes into 570 1 times with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 159468.1
If we subtract 515 from 570, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
The number 515 fits into 550 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 159468.11
Subtract 515 from 550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 159468.11 and a remainder of 0.035.
