517450 ÷ 10 
We want to figure out the number of times 517450 can be divided by 10.

Let's proceed to step 1:
When dividing 5 by 10, we get 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 10

Going ahead to step 2:
51 divided by 10 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 50 from 51 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 10

Going ahead to step 3:
17 divided by 10 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we take 10 away from 17, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 10

Step 4:
When dividing 74 by 10, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 517.0
If we take 70 away from 74, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 10

Step 5:
If we divide 45 by 10, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 5174.0
If we subtract 40 from 45, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 10

Step 6:
The number 10 fits into 50 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 51745.0
If we take 50 away from 50, 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.

Going ahead to step 7:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51745.0
Subtract 0 from 0 to get 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 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51745.0
The remainder is 0 after subtracting 0 from 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 outcome is 51745.0, with a leftover of 0.0.
