If we divide 6 by 518, we get 0 and 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.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 518

Advancing to step 2:
61 divided by 518 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 518

Advancing to step 3:
518 goes into 618 1 times with a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 518 from 618 leaves us with 100.
Grab the next digit (0) from the dividend, add it to 100, then carry on: 1000 / 518

Step 4:
1000 divided by 518 is 1 with a remainder of 482.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 518 from 1000 and we're left with 482.
Bring next digit (9) of the dividend behind the 482 and repeat the process: 4829 / 518

Going ahead to step 5:
If we divide 4829 by 518, we get 9 and a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 4662 from 4829 and we're left with 167.
Fetch the next digit (3) from the dividend, attach it to 167 and continue: 1673 / 518

Let's proceed to step 6:
518 goes into 1673 3 times with a remainder of 119.
Write down 3 as next digit of the result. 
Result so far: 1193.0
Deduct 1554 from 1673 and we're left with 119.
Fetch the next digit (7) from the dividend, attach it to 119 and continue: 1197 / 518

Moving on to step 7:
If we divide 1197 by 518, we get 2 and a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 11932.0
If we take 1036 away from 1197, we end up with 161.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 518

Moving on to step 8:
518 goes into 1619 3 times with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 119323.0
If we subtract 1554 from 1619, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
518 goes into 650 1 times with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 119323.1
Subtracting 518 from 650 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
1320 divided by 518 is 2 with a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 119323.12
Subtract 1036 from 1320 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
2840 divided by 518 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 119323.125
Subtracting 2590 from 2840 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
518 can be fit into 2500 4 times, resulting in a remainder of 428.
The next digit of our result is 4. 
Result so far: 119323.1254
The remainder is 428 after subtracting 2072 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 13:
518 goes into 4280 8 times with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 119323.12548
If we subtract 4144 from 4280, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
When dividing 1360 by 518, we get 2 with a remainder of 324.
The next digit of our result is 2. 
Result so far: 119323.125482
Subtracting 1036 from 1360 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 15:
518 can be fit into 3240 6 times, resulting in a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 119323.1254826
The remainder is 132 after subtracting 3108 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 16:
When dividing 1320 by 518, we get 2 with a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 119323.12548262
If we subtract 1036 from 1320, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 119323.12548262 with a remainder of 2.84e-07.
