We divide 644552 by 2
We want to divide 644552 by 2.

Advancing to step 1:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Let's proceed to step 2:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Step 3:
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: 322.0
Subtract 4 from 4 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Moving on to step 4:
If we divide 5 by 2, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 3222.0
If we take 4 away from 5, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Going ahead to step 5:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 32227.0
Subtract 14 from 15 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Moving on to step 6:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 322276.0
If we subtract 12 from 12, 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.

Advancing to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 322276.0
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 322276.0
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.

Our division results in 322276.0 with a remaining 0.0.
