43495851 divided by 2 
Our goal is to divide 43495851 by 2.

Going ahead to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Moving on to step 2:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 2 from 3 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Advancing to step 3:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 217.0
The remainder is 0 after subtracting 14 from 14.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

On to step 4:
9 divided by 2 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2174.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

On to step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 21747.0
Subtracting 14 from 15 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 217479.0
Subtracting 18 from 18 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Going ahead to step 7:
5 divided by 2 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2174792.0
Subtract 4 from 5 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Step 8:
If we divide 11 by 2, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 21747925.0
Subtract 10 from 11 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.

Step 9:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 21747925.5
Deduct 10 from 10 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.

Moving on to step 10:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21747925.5
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.

Let's proceed to step 11:
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: 21747925.5
If we subtract 0 from 0, 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.

The final outcome is 21747925.5, with a leftover of 0.0.
