We look at the division of 43148 by 15 
We're looking to find how many times 15 goes into 43148.

Moving on to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Step 2:
15 goes into 43 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 43, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 15

Let's proceed to step 3:
15 can be fit into 131 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 120 from 131 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 15

Step 4:
15 goes into 114 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 287.0
If we take 105 away from 114, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 15

Let's proceed to step 5:
98 divided by 15 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2876.0
If we subtract 90 from 98, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 6:
If we divide 80 by 15, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2876.5
Subtracting 75 from 80 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 2876.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2876.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 2876.533, and the remainder is 0.0005.
