We divide 312584 by 15
Our goal is to divide 312584 by 15.

Let's proceed to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 15

Moving on to step 2:
If we divide 31 by 15, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 30 away from 31, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

Advancing to step 3:
15 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 12, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 15

Let's proceed to step 4:
125 divided by 15 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Deduct 120 from 125 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 15

On to step 5:
15 goes into 58 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2083.0
The remainder is 13 after subtracting 45 from 58.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Moving on to step 6:
134 divided by 15 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 20838.0
If we take 120 away from 134, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 20838.9
Deduct 135 from 140 and we're left 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:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 20838.93
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.

Advancing to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 20838.933
If we take 45 away from 50, we end up 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 20838.933, and the remainder is 0.0005.
