242579 divided by 2 
We're looking to find how many times 2 goes into 242579.

Step 1:
2 goes into 2 1 times 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.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Advancing to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Moving on to step 3:
2 goes into 2 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

On to step 4:
2 goes into 5 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1212.0
If we take 4 away from 5, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

On to step 5:
2 can be fit into 17 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 12128.0
Subtract 16 from 17 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Step 6:
19 divided by 2 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 121289.0
Deduct 18 from 19 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.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 121289.5
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 121289.5
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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 121289.5
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.

After the division, we end up with 121289.5 and a remainder of 0.0.
