81918344 ÷ 518 
Let's see how many times 518 fits into 81918344.

Going ahead to step 1:
8 divided by 518 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 518

On to step 2:
518 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 518

Going ahead to step 3:
518 goes into 819 1 times with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 518 away from 819, we end up with 301.
Take the next digit (1) from the dividend and append it to 301, then repeat: 3011 / 518

Moving on to step 4:
The number 518 fits into 3011 5 times, leaving a remainder of 421.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2590 from 3011 and we're left with 421.
Fetch the next digit (8) from the dividend, attach it to 421 and continue: 4218 / 518

Let's proceed to step 5:
518 goes into 4218 8 times with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Subtract 4144 from 4218 to get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 518

On to step 6:
When dividing 743 by 518, we get 1 with a remainder of 225.
Record the quotient 1 as the next digit in the result. 
Result so far: 1581.0
Subtracting 518 from 743 leaves us with 225.
Include the next digit (4) from the dividend after 225, then repeat: 2254 / 518

Advancing to step 7:
When dividing 2254 by 518, we get 4 with a remainder of 182.
The next digit of our result is 4. 
Result so far: 15814.0
Subtract 2072 from 2254 to get 182.
Fetch the next digit (4) from the dividend, attach it to 182 and continue: 1824 / 518

Moving on to step 8:
If we divide 1824 by 518, we get 3 and a remainder of 270.
Put 3 as the next digit of the answer. 
Result so far: 158143.0
Subtracting 1554 from 1824 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 9:
If we divide 2700 by 518, we get 5 and a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 158143.5
The remainder is 110 after subtracting 2590 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
The number 518 fits into 1100 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 158143.52
Deduct 1036 from 1100 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
518 can be fit into 640 1 times, resulting in a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 158143.521
If we subtract 518 from 640, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
The number 518 fits into 1220 2 times, leaving a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 158143.5212
Deduct 1036 from 1220 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
The number 518 fits into 1840 3 times, leaving a remainder of 286.
Record the quotient 3 as the next digit in the result. 
Result so far: 158143.52123
If we subtract 1554 from 1840, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 14:
If we divide 2860 by 518, we get 5 and a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 158143.521235
The remainder is 270 after subtracting 2590 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 15:
When dividing 2700 by 518, we get 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 158143.5212355
Subtracting 2590 from 2700 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 158143.5212355 with a balance of 1.1e-06.
