We look at the division of 666513 by 52 
Let's see how many times 52 fits into 666513.

On to step 1:
52 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 52

Going ahead to step 2:
When dividing 66 by 52, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 14 after subtracting 52 from 66.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 52

Let's proceed to step 3:
146 divided by 52 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 104 from 146, we get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 52

Going ahead to step 4:
52 can be fit into 425 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 416 from 425 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 52

Moving on to step 5:
If we divide 91 by 52, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1281.0
Subtracting 52 from 91 leaves us with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 52

On to step 6:
When dividing 393 by 52, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 12817.0
Subtracting 364 from 393 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
290 divided by 52 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 12817.5
If we subtract 260 from 290, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 52 fits into 300 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 12817.55
Deduct 260 from 300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 12817.55, with a leftover of 0.04.
