Let's divide 285799 by 15
Our goal is to divide 285799 by 15.

Let's proceed to step 1:
The number 15 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 15

Going ahead to step 2:
The number 15 fits into 28 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 15 from 28.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Moving on to step 3:
If we divide 135 by 15, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 135 from 135 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 15

Advancing to step 4:
7 divided by 15 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 15

Moving on to step 5:
When dividing 79 by 15, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 1905.0
If we take 75 away from 79, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Moving on to step 6:
The number 15 fits into 49 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 19053.0
Deduct 45 from 49 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 15 fits into 40 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 19053.2
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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 19053.26
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 19053.266
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 19053.266 and a remainder of 0.001.
