391029 divided by 2 
We want to figure out the number of times 391029 can be divided by 2.

Moving on to step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 2 from 3 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Let's proceed to step 2:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

On to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Subtracting 10 from 11 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Let's proceed to step 4:
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: 1955.0
If we take 10 away from 10, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Going ahead to step 5:
2 divided by 2 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 19551.0
If we subtract 2 from 2, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Step 6:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 195514.0
If we take 8 away from 9, we end up 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.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 195514.5
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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 195514.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 195514.5
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.

In conclusion, the division gives 195514.5 with a balance of 0.0.
