We look at the division of 515175 by 10 
We want to figure out the number of times 515175 can be divided by 10.

Step 1:
The number 10 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 10

Let's proceed to step 2:
The number 10 fits into 51 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 50 from 51 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 10

Let's proceed to step 3:
If we divide 15 by 10, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 10 from 15 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 10

Step 4:
When dividing 51 by 10, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 515.0
If we subtract 50 from 51, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 10

Step 5:
The number 10 fits into 17 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 5151.0
Deduct 10 from 17 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 10

Going ahead to step 6:
When dividing 75 by 10, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 51517.0
Subtract 70 from 75 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 10, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 51517.5
Subtract 50 from 50 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.

Step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 51517.5
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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51517.5
Deduct 0 from 0 and we're left 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.

After the division, we end up with 51517.5 and a remainder of 0.0.
