We look at the division of 2143 by 15 
Our goal is to divide 2143 by 15.

Step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 15

Step 2:
If we divide 21 by 15, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 15 from 21.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 15

On to step 3:
15 can be fit into 64 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 60 from 64 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 15

Advancing to step 4:
If we divide 43 by 15, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 13 after subtracting 30 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 5:
If we divide 130 by 15, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 142.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 142.86
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 142.866
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 142.866, with a leftover of 0.001.
