We divide 256715 by 3
We want to figure out the number of times 256715 can be divided by 3.

Let's proceed to step 1:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Going ahead to step 2:
When dividing 25 by 3, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 24 away from 25, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

On to step 3:
The number 3 fits into 16 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 15 from 16 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Going ahead to step 4:
When dividing 17 by 3, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 855.0
Deduct 15 from 17 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Step 5:
If we divide 21 by 3, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 8557.0
The remainder is 0 after subtracting 21 from 21.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

On to step 6:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 85571.0
If we take 3 away from 5, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 85571.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 85571.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 85571.66, with a leftover of 0.002.
