We're dividing 361889 by 2 
We're looking to find how many times 2 goes into 361889.

On to step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 2:
When dividing 16 by 2, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 16 from 16, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Going ahead to step 3:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 4:
18 divided by 2 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1809.0
Deduct 18 from 18 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Let's proceed to step 5:
If we divide 8 by 2, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 18094.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

On to step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 180944.0
Subtract 8 from 9 to 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.

Going ahead to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 180944.5
Deduct 10 from 10 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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 180944.5
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.

Going ahead to step 9:
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: 180944.5
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.

The final result is 180944.5 with a remainder of 0.0.
