288190 divided by 15 
Let's see how many times 15 fits into 288190.

Step 1:
2 divided by 15 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

Going ahead to step 2:
If we divide 28 by 15, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 15 from 28 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 15

Moving on to step 3:
The number 15 fits into 138 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 135 away from 138, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

On to step 4:
When dividing 31 by 15, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 192.0
Subtract 30 from 31 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

Step 5:
The number 15 fits into 19 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1921.0
If we take 15 away from 19, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

Moving on to step 6:
40 divided by 15 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 19212.0
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 19212.6
If we subtract 90 from 100, 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.

Let's proceed to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 19212.66
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 result is 19212.66 with a remainder of 0.01.
