We're dividing 721125 by 2 
Our goal is to divide 721125 by 2.

Advancing to step 1:
If we divide 7 by 2, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 2:
2 goes into 12 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 0 after subtracting 12 from 12.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 3:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 360.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 3605.0
Subtract 10 from 11 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

On to step 5:
If we divide 12 by 2, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 36056.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Moving on to step 6:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 360562.0
The remainder is 1 after subtracting 4 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 360562.5
If we take 10 away from 10, 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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 360562.5
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.

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: 360562.5
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.

The quotient of the division is 360562.5, and the remainder is 0.0.
