412823 ÷ 15 
We want to figure out the number of times 412823 can be divided by 15.

Let's proceed to step 1:
4 divided by 15 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 15

On to step 2:
15 can be fit into 41 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 11 after subtracting 30 from 41.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 15

Moving on to step 3:
112 divided by 15 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 7 after subtracting 105 from 112.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Going ahead to step 4:
When dividing 78 by 15, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 275.0
The remainder is 3 after subtracting 75 from 78.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 15

On to step 5:
The number 15 fits into 32 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2752.0
If we take 30 away from 32, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 15

Going ahead to step 6:
23 divided by 15 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 27521.0
If we subtract 15 from 23, 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.

Moving on to step 7:
15 can be fit into 80 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 27521.5
Subtracting 75 from 80 leaves us with 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 8:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 27521.53
Subtract 45 from 50 to 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:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 27521.533
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 27521.533, and the remainder is 0.0005.
