We divide 521276 by 2
We want to figure out the number of times 521276 can be divided by 2.

Moving on to step 1:
If we divide 5 by 2, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Let's proceed to step 2:
When dividing 12 by 2, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Step 3:
1 divided by 2 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 260.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Advancing to step 4:
12 divided by 2 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2606.0
If we take 12 away from 12, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Going ahead to step 5:
When dividing 7 by 2, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 26063.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Moving on to step 6:
When dividing 16 by 2, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 260638.0
If we take 16 away from 16, 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.
Put 0 as the next digit of the answer. 
Result so far: 260638.0
Subtracting 0 from 0 leaves us 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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 260638.0
Subtracting 0 from 0 leaves us 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 260638.0, with a leftover of 0.0.
