Let's divide 783865 by 15
We want to divide 783865 by 15.

Moving on to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 15

Advancing to step 2:
If we divide 78 by 15, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 75 from 78 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 15

Moving on to step 3:
The number 15 fits into 33 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 30 from 33 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 15

Going ahead to step 4:
The number 15 fits into 38 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 522.0
Subtract 30 from 38 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

Moving on to step 5:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5225.0
If we take 75 away from 86, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 15

Advancing to step 6:
If we divide 115 by 15, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 52257.0
Deduct 105 from 115 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.

Advancing to step 7:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 52257.6
Subtracting 90 from 100 leaves us 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.

Going ahead to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 52257.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 52257.66 with a remainder of 0.01.
