285276 ÷ 15 
We want to figure out the number of times 285276 can be divided by 15.

Going ahead to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 15

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
The remainder is 13 after subtracting 15 from 28.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 15

Going ahead to step 3:
15 can be fit into 135 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 135 away from 135, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 15

Going ahead to step 4:
2 divided by 15 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 190.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 15

Going ahead to step 5:
27 divided by 15 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1901.0
The remainder is 12 after subtracting 15 from 27.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 15

Step 6:
When dividing 126 by 15, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19018.0
The remainder is 6 after subtracting 120 from 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 15, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 19018.4
Subtract 60 from 60 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.

Advancing to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19018.4
Deduct 0 from 0 and we're left 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.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 19018.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19018.4 and a remainder of 0.0.
