We divide 517918 by 5
We want to figure out the number of times 517918 can be divided by 5.

Let's proceed to step 1:
The number 5 fits into 5 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 5 away from 5, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 5

Going ahead to step 2:
5 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 5

Moving on to step 3:
5 goes into 17 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 5

Moving on to step 4:
5 can be fit into 29 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1035.0
Subtract 25 from 29 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 5

On to step 5:
5 can be fit into 41 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 10358.0
The remainder is 1 after subtracting 40 from 41.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 5

Step 6:
If we divide 18 by 5, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 103583.0
Subtracting 15 from 18 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 103583.6
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 5 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 103583.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 103583.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 103583.6 with a remainder of 0.0.
