We divide 781899 by 2
We're looking to find how many times 2 goes into 781899.

Going ahead to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 6 from 7, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Advancing to step 2:
18 divided by 2 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Advancing to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 390.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Advancing to step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 3909.0
If we take 18 away from 18, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Moving on to step 5:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 39094.0
Subtract 8 from 9 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Step 6:
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: 390949.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 390949.5
The remainder is 0 after subtracting 10 from 10.
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:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 390949.5
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.

Moving on to step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 390949.5
Subtract 0 from 0 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.

The final outcome is 390949.5, with a leftover of 0.0.
