We look at the division of 520481 by 1 
Let's see how many times 1 fits into 520481.

Step 1:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

On to step 2:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 3:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Let's proceed to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 5204.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 52048.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 6:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 520481.0
Deduct 1 from 1 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.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 520481.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 520481.0
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.

The final outcome is 520481.0, with a leftover of 0.0.
