89166663 divided by 2 
Our goal is to divide 89166663 by 2.

Moving on to step 1:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 2:
If we divide 9 by 2, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Going ahead to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 445.0
Deduct 10 from 11 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Step 4:
2 goes into 16 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4458.0
Subtract 16 from 16 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Going ahead to step 5:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 44583.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Moving on to step 6:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 445833.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Step 7:
2 goes into 6 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4458333.0
If we take 6 away from 6, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Let's proceed to step 8:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 44583331.0
If we take 2 away from 3, 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:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 44583331.5
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.

On to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 44583331.5
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.

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: 44583331.5
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 final outcome is 44583331.5, with a leftover of 0.0.
