Let's divide 81349601 by 2
Let's see how many times 2 fits into 81349601.

On to step 1:
2 goes into 8 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Going ahead to step 2:
2 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Step 3:
13 divided by 2 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 406.0
If we take 12 away from 13, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Going ahead to step 4:
2 goes into 14 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 4067.0
If we take 14 away from 14, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 5:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 40674.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

Let's proceed to step 6:
2 goes into 16 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 406748.0
The remainder is 0 after subtracting 16 from 16.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4067480.0
If we subtract 0 from 0, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 8:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40674800.0
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.

Step 9:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40674800.5
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.

Advancing to step 10:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40674800.5
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.

Let's proceed to step 11:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40674800.5
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.

The final result is 40674800.5 with a remainder of 0.0.
