We look at the division of 75839509 by 2 
We're looking to find how many times 2 goes into 75839509.

Moving on to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 6 from 7, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 2:
2 goes into 15 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 14 from 15 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Moving on to step 3:
2 goes into 18 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 379.0
If we subtract 18 from 18, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

On to step 4:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 3791.0
If we take 2 away from 3, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Moving on to step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 37919.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Advancing to step 6:
15 divided by 2 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 379197.0
If we subtract 14 from 15, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Advancing to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 3791975.0
Subtract 10 from 10 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Going ahead to step 8:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 37919754.0
If we subtract 8 from 9, we 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.

Advancing to step 9:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 37919754.5
Subtract 10 from 10 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.

Going ahead to step 10:
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: 37919754.5
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.

Going ahead to step 11:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37919754.5
The remainder is 0 after subtracting 0 from 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 37919754.5 with a remainder of 0.0.
