38686714 ÷ 518 
Our goal is to divide 38686714 by 518.

Step 1:
3 divided by 518 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 518

Advancing to step 2:
38 divided by 518 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 518

Advancing to step 3:
When dividing 386 by 518, we get 0 with a remainder of 386.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Append the next digit (8) from the dividend to 386 and continue with: 3868 / 518

Going ahead to step 4:
3868 divided by 518 is 7 with a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 3626 from 3868, we get 242.
Append the next digit (6) from the dividend to 242 and continue with: 2426 / 518

Going ahead to step 5:
518 can be fit into 2426 4 times, resulting in a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 2072 from 2426 and we're left with 354.
Append the next digit (7) from the dividend to 354 and continue with: 3547 / 518

Step 6:
518 can be fit into 3547 6 times, resulting in a remainder of 439.
Write down 6 as next digit of the result. 
Result so far: 746.0
Subtract 3108 from 3547 to get 439.
Bring next digit (1) of the dividend behind the 439 and repeat the process: 4391 / 518

Step 7:
If we divide 4391 by 518, we get 8 and a remainder of 247.
The next digit of our result is 8. 
Result so far: 7468.0
Deduct 4144 from 4391 and we're left with 247.
Grab the next digit (4) from the dividend, add it to 247, then carry on: 2474 / 518

Let's proceed to step 8:
518 goes into 2474 4 times with a remainder of 402.
Record the quotient 4 as the next digit in the result. 
Result so far: 74684.0
The remainder is 402 after subtracting 2072 from 2474.
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 9:
4020 divided by 518 is 7 with a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 74684.7
Subtracting 3626 from 4020 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
If we divide 3940 by 518, we get 7 and a remainder of 314.
Put 7 as the next digit of the answer. 
Result so far: 74684.77
If we subtract 3626 from 3940, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final outcome is 74684.77, with a leftover of 0.314.
