Let's divide 91993045 by 2
We're looking to find how many times 2 goes into 91993045.

Step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Let's proceed to step 2:
2 goes into 11 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 1 after subtracting 10 from 11.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Moving on to step 3:
When dividing 19 by 2, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 459.0
If we subtract 18 from 19, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Moving on to step 4:
The number 2 fits into 19 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 4599.0
Deduct 18 from 19 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

On to step 5:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 45996.0
If we take 12 away from 13, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Step 6:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 459965.0
Deduct 10 from 10 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Advancing to step 7:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4599652.0
If we subtract 4 from 4, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 8:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 45996522.0
If we take 4 away from 5, 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.

Let's proceed to step 9:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45996522.5
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.

Advancing to step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45996522.5
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.

Moving on to step 11:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45996522.5
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.

The quotient of the division is 45996522.5, and the remainder is 0.0.
