258299 divided by 2 
We're looking to find how many times 2 goes into 258299.

Moving on to step 1:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Let's proceed to step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 4 from 5 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 3:
If we divide 18 by 2, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 18 from 18 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Going ahead to step 4:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1291.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Let's proceed to step 5:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 12914.0
If we take 8 away from 9, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Advancing to step 6:
2 goes into 19 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 129149.0
If we take 18 away from 19, 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 129149.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 129149.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 129149.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 129149.5 with a remaining 0.0.
