We're dividing 721293 by 2 
Let's see how many times 2 fits into 721293.

Going ahead to step 1:
If we divide 7 by 2, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 6 from 7 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Step 2:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Moving on to step 3:
1 divided by 2 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 360.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Going ahead to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 3606.0
If we subtract 12 from 12, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Moving on to step 5:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 36064.0
Deduct 8 from 9 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

On to step 6:
If we divide 13 by 2, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 360646.0
Subtract 12 from 13 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.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 360646.5
If we subtract 10 from 10, 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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 360646.5
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.

Going ahead to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 360646.5
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.

Our division results in 360646.5 with a remaining 0.0.
