517045 ÷ 4 
We want to figure out the number of times 517045 can be divided by 4.

Going ahead to step 1:
5 divided by 4 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 4 from 5 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 4

Advancing to step 2:
4 goes into 11 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 8 from 11 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

Let's proceed to step 3:
The number 4 fits into 37 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtract 36 from 37 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Step 4:
4 goes into 10 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1292.0
If we subtract 8 from 10, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 4

Moving on to step 5:
The number 4 fits into 24 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 12926.0
Subtracting 24 from 24 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Let's proceed to step 6:
4 goes into 5 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 129261.0
The remainder is 1 after subtracting 4 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 4 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 129261.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 129261.25
Subtracting 20 from 20 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.

Moving on to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 129261.25
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.

Advancing to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 129261.25
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.

Our division results in 129261.25 with a remaining 0.0.
