143 ÷ 13 
We want to divide 143 by 13.

On to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 13

Step 2:
13 goes into 14 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 13 from 14.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 13

Going ahead to step 3:
The number 13 fits into 13 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 0 after subtracting 13 from 13.
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 4:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11.0
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.

Let's proceed to step 5:
13 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11.0
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.

The final result is 11.0 with a remainder of 0.0.
