We're dividing 517505 by 45 
We're looking to find how many times 45 goes into 517505.

Moving on to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Step 2:
45 can be fit into 51 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 51 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

Going ahead to step 3:
The number 45 fits into 67 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 45 from 67 leaves us with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 45

Moving on to step 4:
When dividing 225 by 45, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtract 225 from 225 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 45

Advancing to step 5:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1150.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 45

Advancing to step 6:
The number 45 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 11500.0
If we subtract 0 from 5, we 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.

Moving on to step 7:
45 goes into 50 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11500.1
Subtract 45 from 50 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 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11500.11
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 11500.11 and a remainder of 0.005.
