We divide 289887 by 2
We want to figure out the number of times 289887 can be divided by 2.

Let's proceed to step 1:
2 goes into 2 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Going ahead to step 2:
If we divide 8 by 2, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Deduct 8 from 9 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Advancing to step 4:
When dividing 18 by 2, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1449.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Advancing to step 5:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14494.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Advancing to step 6:
7 divided by 2 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 144943.0
If we subtract 6 from 7, 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.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 144943.5
If we subtract 10 from 10, 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 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 144943.5
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.

On to step 9:
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: 144943.5
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.

Our division results in 144943.5 with a remaining 0.0.
