We look at the division of 75491 by 2 
We want to figure out the number of times 75491 can be divided by 2.

Step 1:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 6 from 7 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 14 from 15 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 3:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 377.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Advancing to step 4:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 3774.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Going ahead to step 5:
11 divided by 2 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 37745.0
If we take 10 away from 11, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 6:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 37745.5
The remainder is 0 after subtracting 10 from 10.
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 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37745.5
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37745.5
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 result is 37745.5 with a remainder of 0.0.
