We're dividing 990313 by 2 
We want to divide 990313 by 2.

On to step 1:
9 divided by 2 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Advancing to step 2:
When dividing 19 by 2, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 49.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Moving on to step 3:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
Subtract 10 from 10 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Moving on to step 4:
When dividing 3 by 2, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4951.0
If we take 2 away from 3, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 5:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 49515.0
Subtract 10 from 11 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Moving on to step 6:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 495156.0
Subtracting 12 from 13 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 495156.5
Subtract 10 from 10 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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 495156.5
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.

Advancing to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 495156.5
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.

Our division results in 495156.5 with a remaining 0.0.
