Let's divide 258013 by 3
We want to divide 258013 by 3.

Going ahead to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Going ahead to step 2:
25 divided by 3 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 24 from 25, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 3:
18 divided by 3 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 18 from 18 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 4:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 860.0
Subtract 0 from 0 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 5:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 8600.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Advancing to step 6:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 86004.0
Deduct 12 from 13 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.

On to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 86004.3
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.

Moving on to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 86004.33
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.

After the division, we end up with 86004.33 and a remainder of 0.001.
