258526 divided by 3 
Our goal is to divide 258526 by 3.

Advancing to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Advancing to step 2:
3 can be fit into 25 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 24 from 25 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Step 3:
18 divided by 3 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 18 from 18 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

On to step 4:
The number 3 fits into 5 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 861.0
Subtract 3 from 5 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Let's proceed to step 5:
3 goes into 22 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 8617.0
If we take 21 away from 22, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

On to step 6:
The number 3 fits into 16 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 86175.0
Subtract 15 from 16 to 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.

Going ahead to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 86175.3
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.

On to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 86175.33
Deduct 9 from 10 and we're left 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.

The final result is 86175.33 with a remainder of 0.001.
