629945 ÷ 2 
We want to figure out the number of times 629945 can be divided by 2.

Advancing to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Let's proceed to step 2:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Advancing to step 3:
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: 314.0
Subtract 8 from 9 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Moving on to step 4:
2 goes into 19 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3149.0
If we take 18 away from 19, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Moving on to step 5:
When dividing 14 by 2, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 31497.0
Subtract 14 from 14 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Step 6:
5 divided by 2 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 314972.0
If we subtract 4 from 5, we 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.

Going ahead to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 314972.5
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.

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: 314972.5
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.

Advancing to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 314972.5
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.

The final result is 314972.5 with a remainder of 0.0.
