We divide 691258 by 2
We're looking to find how many times 2 goes into 691258.

Step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Moving on to step 2:
When dividing 9 by 2, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 8 away from 9, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
If we subtract 10 from 11, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Moving on to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 3456.0
Subtract 12 from 12 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Let's proceed to step 5:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 34562.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

On to step 6:
18 divided by 2 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 345629.0
If we take 18 away from 18, we end up 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.

Moving on to step 7:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 345629.0
Deduct 0 from 0 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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 345629.0
If we take 0 away from 0, we end up 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.

Our division results in 345629.0 with a remaining 0.0.
