We divide 271621 by 2
We want to figure out the number of times 271621 can be divided by 2.

Going ahead to step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

Advancing to step 2:
If we divide 7 by 2, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 6 from 7 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Let's proceed to step 3:
If we divide 11 by 2, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 10 from 11 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Step 4:
When dividing 16 by 2, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1358.0
Subtracting 16 from 16 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 13581.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

On to step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 135810.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 135810.5
Subtracting 10 from 10 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.

Step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 135810.5
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.

Advancing to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 135810.5
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 result is 135810.5 with a remainder of 0.0.
