81609277 ÷ 518 
We want to figure out the number of times 81609277 can be divided by 518.

On to step 1:
518 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 518

On to step 2:
81 divided by 518 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 518

Going ahead to step 3:
When dividing 816 by 518, we get 1 with a remainder of 298.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 298 after subtracting 518 from 816.
Append the next digit (0) from the dividend to 298 and continue with: 2980 / 518

Let's proceed to step 4:
If we divide 2980 by 518, we get 5 and a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2590 from 2980, we get 390.
Append the next digit (9) from the dividend to 390 and continue with: 3909 / 518

Step 5:
The number 518 fits into 3909 7 times, leaving a remainder of 283.
Write down 7 as next digit of the result. 
Result so far: 157.0
Deduct 3626 from 3909 and we're left with 283.
Take the next digit (2) from the dividend and append it to 283, then repeat: 2832 / 518

Step 6:
518 goes into 2832 5 times with a remainder of 242.
Put 5 as the next digit of the answer. 
Result so far: 1575.0
If we take 2590 away from 2832, we end up with 242.
Fetch the next digit (7) from the dividend, attach it to 242 and continue: 2427 / 518

Step 7:
The number 518 fits into 2427 4 times, leaving a remainder of 355.
Use 4 as the next digit of our solution. 
Result so far: 15754.0
If we subtract 2072 from 2427, we get 355.
Fetch the next digit (7) from the dividend, attach it to 355 and continue: 3557 / 518

Advancing to step 8:
518 goes into 3557 6 times with a remainder of 449.
Put 6 as the next digit of the answer. 
Result so far: 157546.0
Deduct 3108 from 3557 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
The number 518 fits into 4490 8 times, leaving a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 157546.8
Subtract 4144 from 4490 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 10:
518 can be fit into 3460 6 times, resulting in a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 157546.86
Subtract 3108 from 3460 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 11:
3520 divided by 518 is 6 with a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 157546.866
Subtracting 3108 from 3520 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The quotient of the division is 157546.866, and the remainder is 0.0412.
