We're dividing 28858 by 15 
Let's see how many times 15 fits into 28858.

Going ahead to step 1:
2 divided by 15 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 15

Advancing to step 2:
15 goes into 28 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 15 from 28, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 15

Let's proceed to step 3:
The number 15 fits into 138 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 135 away from 138, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

On to step 4:
The number 15 fits into 35 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we take 30 away from 35, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 15

Let's proceed to step 5:
If we divide 58 by 15, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 1923.0
If we subtract 45 from 58, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
If we divide 130 by 15, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 1923.8
Subtracting 120 from 130 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.

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: 1923.86
The remainder is 10 after subtracting 90 from 100.
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 8:
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: 1923.866
Deduct 90 from 100 and we're left 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.

After the division, we end up with 1923.866 and a remainder of 0.001.
