89583329 ÷ 2 
We want to divide 89583329 by 2.

Let's proceed to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

On to step 2:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Let's proceed to step 3:
If we divide 15 by 2, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 447.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

On to step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4479.0
The remainder is 0 after subtracting 18 from 18.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Let's proceed to step 5:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 44791.0
Subtract 2 from 3 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Advancing to step 6:
When dividing 13 by 2, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 447916.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

On to step 7:
When dividing 12 by 2, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 4479166.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 8:
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: 44791664.0
Deduct 8 from 9 and we're left 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.

Going ahead to step 9:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 44791664.5
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.

Moving on to step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44791664.5
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.

Moving on to step 11:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 44791664.5
Subtracting 0 from 0 leaves us 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 44791664.5, with a leftover of 0.0.
