538121 ÷ 2 
Let's see how many times 2 fits into 538121.

Moving on to step 1:
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: 2.0
Subtract 4 from 5 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Advancing to step 2:
If we divide 13 by 2, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 12 from 13 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 269.0
Subtract 18 from 18 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Advancing to step 4:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 2690.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Let's proceed to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 26906.0
Subtracting 12 from 12 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Advancing to step 6:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 269060.0
Subtracting 0 from 1 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 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 269060.5
If we subtract 10 from 10, 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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 269060.5
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.

Advancing to step 9:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 269060.5
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.

In conclusion, the division gives 269060.5 with a balance of 0.0.
