849980 ÷ 2 
Let's see how many times 2 fits into 849980.

Let's proceed to step 1:
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: 4.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Advancing to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Advancing to step 3:
2 goes into 9 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 424.0
If we subtract 8 from 9, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Advancing to step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4249.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Advancing to step 5:
When dividing 18 by 2, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 42499.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Moving on to step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 424990.0
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.

Let's proceed to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 424990.0
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.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 424990.0
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.

After the division, we end up with 424990.0 and a remainder of 0.0.
