8521049 ÷ 518 
We want to figure out the number of times 8521049 can be divided by 518.

Step 1:
The number 518 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 518

Moving on to step 2:
If we divide 85 by 518, we get 0 and a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 518

Moving on to step 3:
The number 518 fits into 852 1 times, leaving a remainder of 334.
The next digit of our result is 1. 
Result so far: 1.0
If we take 518 away from 852, we end up with 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 518

Moving on to step 4:
518 can be fit into 3341 6 times, resulting in a remainder of 233.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 3108 from 3341, we get 233.
Bring next digit (0) of the dividend behind the 233 and repeat the process: 2330 / 518

Going ahead to step 5:
2330 divided by 518 is 4 with a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 2072 away from 2330, we end up with 258.
Include the next digit (4) from the dividend after 258, then repeat: 2584 / 518

Step 6:
When dividing 2584 by 518, we get 4 with a remainder of 512.
Use 4 as the next digit of our solution. 
Result so far: 1644.0
If we subtract 2072 from 2584, we get 512.
Fetch the next digit (9) from the dividend, attach it to 512 and continue: 5129 / 518

Moving on to step 7:
518 goes into 5129 9 times with a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 16449.0
Subtract 4662 from 5129 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 8:
4670 divided by 518 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 16449.9
Subtracting 4662 from 4670 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
518 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 16449.9
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 518, we get 1 and a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 16449.901
If we subtract 518 from 800, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
518 can be fit into 2820 5 times, resulting in a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 16449.9015
Subtracting 2590 from 2820 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
518 goes into 2300 4 times with a remainder of 228.
The next digit of our result is 4. 
Result so far: 16449.90154
Subtract 2072 from 2300 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 13:
If we divide 2280 by 518, we get 4 and a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 16449.901544
Deduct 2072 from 2280 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 16449.901544, with a leftover of 2.08e-05.
