517408 ÷ 4 
Our goal is to divide 517408 by 4.

Advancing to step 1:
4 goes into 5 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 4 away from 5, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Step 2:
11 divided by 4 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 8 from 11, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Let's proceed to step 3:
4 can be fit into 37 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 36 from 37, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Moving on to step 4:
If we divide 14 by 4, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1293.0
Deduct 12 from 14 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Let's proceed to step 5:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12935.0
Subtract 20 from 20 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Step 6:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 129352.0
Subtract 8 from 8 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.

Let's proceed to step 7:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 129352.0
If we subtract 0 from 0, we 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.

Advancing to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 129352.0
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.

The final outcome is 129352.0, with a leftover of 0.0.
