228578 ÷ 15 
We want to figure out the number of times 228578 can be divided by 15.

Advancing to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 15

Going ahead to step 2:
If we divide 22 by 15, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 15 away from 22, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 15

Advancing to step 3:
When dividing 78 by 15, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 75 from 78 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 15

Let's proceed to step 4:
When dividing 35 by 15, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtract 30 from 35 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 15

Advancing to step 5:
The number 15 fits into 57 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 1523.0
If we take 45 away from 57, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 15

Let's proceed to step 6:
15 can be fit into 128 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 15238.0
If we subtract 120 from 128, 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.

On to step 7:
15 goes into 80 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 15238.5
The remainder is 5 after subtracting 75 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 15238.53
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.

Moving on to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 15238.533
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.

Our division results in 15238.533 with a remaining 0.0005.
