68467681 ÷ 518 
We want to figure out the number of times 68467681 can be divided by 518.

Let's proceed to step 1:
When dividing 6 by 518, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 518

Advancing to step 2:
518 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 518

Let's proceed to step 3:
If we divide 684 by 518, we get 1 and a remainder of 166.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 518 from 684 and we're left with 166.
Append the next digit (6) from the dividend to 166 and continue with: 1666 / 518

On to step 4:
518 goes into 1666 3 times with a remainder of 112.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1554 from 1666 and we're left with 112.
Append the next digit (7) from the dividend to 112 and continue with: 1127 / 518

On to step 5:
518 goes into 1127 2 times with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Deduct 1036 from 1127 and we're left with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 518

Step 6:
The number 518 fits into 916 1 times, leaving a remainder of 398.
Use 1 as the next digit of our solution. 
Result so far: 1321.0
Deduct 518 from 916 and we're left with 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 518

Step 7:
When dividing 3988 by 518, we get 7 with a remainder of 362.
Record the quotient 7 as the next digit in the result. 
Result so far: 13217.0
If we subtract 3626 from 3988, we get 362.
Include the next digit (1) from the dividend after 362, then repeat: 3621 / 518

Advancing to step 8:
If we divide 3621 by 518, we get 6 and a remainder of 513.
Record the quotient 6 as the next digit in the result. 
Result so far: 132176.0
Subtract 3108 from 3621 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 9:
When dividing 5130 by 518, we get 9 with a remainder of 468.
Use 9 as the next digit of our solution. 
Result so far: 132176.9
If we take 4662 away from 5130, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
4680 divided by 518 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 132176.99
Deduct 4662 from 4680 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 132176.99 with a remainder of 0.018.
