54342109 divided by 518 
We're looking to find how many times 518 goes into 54342109.

On to step 1:
5 divided by 518 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 518

Let's proceed to step 2:
54 divided by 518 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 518

Moving on to step 3:
518 can be fit into 543 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 518 from 543 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 518

On to step 4:
254 divided by 518 is 0 with a remainder of 254.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 254, we end up with 254.
Fetch the next digit (2) from the dividend, attach it to 254 and continue: 2542 / 518

On to step 5:
518 can be fit into 2542 4 times, resulting in a remainder of 470.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 470 after subtracting 2072 from 2542.
Append the next digit (1) from the dividend to 470 and continue with: 4701 / 518

Step 6:
4701 divided by 518 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 1049.0
The remainder is 39 after subtracting 4662 from 4701.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 518

On to step 7:
518 can be fit into 390 0 times, resulting in a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 10490.0
Subtract 0 from 390 to get 390.
Include the next digit (9) from the dividend after 390, then repeat: 3909 / 518

On to step 8:
The number 518 fits into 3909 7 times, leaving a remainder of 283.
Put 7 as the next digit of the answer. 
Result so far: 104907.0
Subtracting 3626 from 3909 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 9:
518 can be fit into 2830 5 times, resulting in a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 104907.5
If we take 2590 away from 2830, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
518 can be fit into 2400 4 times, resulting in a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 104907.54
Subtract 2072 from 2400 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
When dividing 3280 by 518, we get 6 with a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 104907.546
If we subtract 3108 from 3280, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 12:
When dividing 1720 by 518, we get 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 104907.5463
The remainder is 166 after subtracting 1554 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 13:
If we divide 1660 by 518, we get 3 and a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 104907.54633
The remainder is 106 after subtracting 1554 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 104907.54633 with a balance of 0.000106.
