91045930 ÷ 2 
We want to divide 91045930 by 2.

Advancing to step 1:
2 goes into 9 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 9, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Moving on to step 2:
2 goes into 11 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 10 from 11 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Advancing to step 3:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 455.0
Subtract 10 from 10 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Step 4:
2 goes into 4 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4552.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Let's proceed to step 5:
If we divide 5 by 2, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 45522.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Let's proceed to step 6:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 455229.0
The remainder is 1 after subtracting 18 from 19.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 7:
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: 4552296.0
Deduct 12 from 13 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 8:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45522965.0
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.

Step 9:
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: 45522965.0
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.

Advancing to step 10:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45522965.0
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 45522965.0 with a remainder of 0.0.
