We're dividing 42453765 by 2 
Our goal is to divide 42453765 by 2.

Going ahead to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 2:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Moving on to step 3:
4 divided by 2 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 212.0
If we take 4 away from 4, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

On to step 4:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2122.0
The remainder is 1 after subtracting 4 from 5.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Going ahead to step 5:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 21226.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Step 6:
The number 2 fits into 17 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 212268.0
Subtracting 16 from 17 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

On to step 7:
When dividing 16 by 2, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2122688.0
If we take 16 away from 16, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 8:
When dividing 5 by 2, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 21226882.0
Subtract 4 from 5 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.

Let's proceed to step 9:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 21226882.5
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.

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: 21226882.5
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.

Moving on to step 11:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21226882.5
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 quotient of the division is 21226882.5, and the remainder is 0.0.
