If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 13

On to step 2:
When dividing 52 by 13, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 0 after subtracting 52 from 52.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 13

On to step 3:
The number 13 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 13

Moving on to step 4:
The number 13 fits into 35 2 times, leaving a remainder of 9.
The next digit of our result is 2. 
Result so far: 402.0
Deduct 26 from 35 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 13

Moving on to step 5:
If we divide 96 by 13, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4027.0
Deduct 91 from 96 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 13

On to step 6:
When dividing 52 by 13, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result.

Use 0 as the next digit of our solution. 
Result so far: 40274.0
Subtract 0 from 0 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.

Going ahead to step 8:
13 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40274.0
Subtracting 0 from 0 leaves us with 0.
