665912 divided by 13 
Our goal is to divide 665912 by 13.

Let's proceed to step 1:
13 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 13

Going ahead to step 2:
66 divided by 13 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 65 away from 66, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 13

Let's proceed to step 3:
15 divided by 13 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 13 from 15, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 13

Going ahead to step 4:
If we divide 29 by 13, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 512.0
Subtracting 26 from 29 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

Advancing to step 5:
If we divide 31 by 13, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 5122.0
Deduct 26 from 31 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 13

Moving on to step 6:
If we divide 52 by 13, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 51224.0
Subtracting 52 from 52 leaves us 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.

Advancing to step 7:
If we divide 0 by 13, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 51224.0
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.

Let's proceed to step 8:
0 divided by 13 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51224.0
Subtracting 0 from 0 leaves us 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 51224.0, with a leftover of 0.0.
