521141 divided by 2 
Let's see how many times 2 fits into 521141.

Step 1:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Let's proceed to step 2:
When dividing 12 by 2, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 260.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2605.0
If we subtract 10 from 11, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Moving on to step 5:
2 goes into 14 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 26057.0
If we take 14 away from 14, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 6:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 260570.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 260570.5
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.

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: 260570.5
The remainder is 0 after subtracting 0 from 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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 260570.5
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.

The final outcome is 260570.5, with a leftover of 0.0.
