381980 ÷ 2 
Let's see how many times 2 fits into 381980.

Step 1:
When dividing 3 by 2, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Let's proceed to step 2:
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: 19.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 190.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Going ahead to step 4:
If we divide 19 by 2, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1909.0
If we subtract 18 from 19, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Let's proceed to step 5:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 19099.0
If we take 18 away from 18, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Going ahead to step 6:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 190990.0
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.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 190990.0
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.

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: 190990.0
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 result is 190990.0 with a remainder of 0.0.
