359868 divided by 15 
We want to divide 359868 by 15.

Let's proceed to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 15

Step 2:
The number 15 fits into 35 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 30 from 35.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 15

Let's proceed to step 3:
15 goes into 59 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 45 from 59, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 15

Going ahead to step 4:
The number 15 fits into 148 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Subtracting 135 from 148 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 15

Advancing to step 5:
15 can be fit into 136 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2399.0
If we subtract 135 from 136, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 15

On to step 6:
15 goes into 18 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 23991.0
If we take 15 away from 18, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 goes into 30 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 23991.2
If we take 30 away from 30, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23991.2
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.

Moving on to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23991.2
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 outcome is 23991.2, with a leftover of 0.0.
