We divide 258271 by 3
We're looking to find how many times 3 goes into 258271.

Advancing to step 1:
3 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Going ahead to step 2:
3 goes into 25 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
If we take 24 away from 25, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Advancing to step 3:
When dividing 18 by 3, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Moving on to step 4:
3 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

On to step 5:
3 can be fit into 27 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 8609.0
The remainder is 0 after subtracting 27 from 27.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Moving on to step 6:
When dividing 1 by 3, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 86090.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 86090.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 86090.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 86090.33 with a remainder of 0.001.
