Let's divide 517455 by 4
We're looking to find how many times 4 goes into 517455.

Step 1:
If we divide 5 by 4, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 4 away from 5, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Advancing to step 2:
When dividing 11 by 4, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 8 from 11 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 4

Advancing to step 3:
If we divide 37 by 4, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 129.0
If we subtract 36 from 37, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 4

On to step 4:
4 can be fit into 14 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1293.0
Subtract 12 from 14 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

Step 5:
25 divided by 4 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 12936.0
Subtracting 24 from 25 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

Step 6:
4 can be fit into 15 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 129363.0
Subtract 12 from 15 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 129363.7
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 129363.75
Deduct 20 from 20 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.

Let's proceed to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 129363.75
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.

Going ahead to step 10:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 129363.75
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.

The quotient of the division is 129363.75, and the remainder is 0.0.
