We look at the division of 90731035 by 2 
We want to divide 90731035 by 2.

Let's proceed to step 1:
If we divide 9 by 2, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 10 from 10 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 2

Going ahead to step 3:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 453.0
If we subtract 6 from 7, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Moving on to step 4:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 4536.0
Subtracting 12 from 13 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Moving on to step 5:
If we divide 11 by 2, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 45365.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Moving on to step 6:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 453655.0
Deduct 10 from 10 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Going ahead to step 7:
2 goes into 3 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4536551.0
Subtracting 2 from 3 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 8:
2 goes into 15 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 45365517.0
If we subtract 14 from 15, 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.

Let's proceed to step 9:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45365517.5
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:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 45365517.5
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.

Step 11:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45365517.5
If we take 0 away from 0, we end up 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.

Our division results in 45365517.5 with a remaining 0.0.
