We're dividing 320678 by 15 
We want to divide 320678 by 15.

Moving on to step 1:
15 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

On to step 2:
When dividing 32 by 15, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 32, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 15

On to step 3:
When dividing 20 by 15, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 15 away from 20, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 15

Step 4:
56 divided by 15 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Deduct 45 from 56 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 15

Step 5:
15 can be fit into 117 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 2137.0
Deduct 105 from 117 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 15

Let's proceed to step 6:
15 can be fit into 128 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 21378.0
Subtracting 120 from 128 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21378.5
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:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 21378.53
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.

Advancing to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 21378.533
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.

The final result is 21378.533 with a remainder of 0.0005.
