Let's divide 813278 by 15
We want to divide 813278 by 15.

Advancing to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 15

Let's proceed to step 2:
15 goes into 81 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 75 away from 81, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

Advancing to step 3:
If we divide 63 by 15, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 60 from 63 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 15

Going ahead to step 4:
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: 542.0
Deduct 30 from 32 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 15

Moving on to step 5:
15 can be fit into 27 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 5421.0
The remainder is 12 after subtracting 15 from 27.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 15

Moving on to step 6:
128 divided by 15 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 54218.0
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.

On to step 7:
15 goes into 80 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 54218.5
Subtract 75 from 80 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.

Going ahead to step 8:
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: 54218.53
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.

Going ahead to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 54218.533
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 54218.533 with a remainder of 0.0005.
