390545 ÷ 2 
We're looking to find how many times 2 goes into 390545.

Let's proceed to step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 2 from 3 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Let's proceed to step 2:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 18 away from 19, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Moving on to step 3:
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: 195.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Step 4:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 1952.0
If we take 4 away from 5, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Let's proceed to step 5:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 19527.0
Subtract 14 from 14 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Let's proceed to step 6:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 195272.0
Subtract 4 from 5 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.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 195272.5
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.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 195272.5
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.

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: 195272.5
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 195272.5 with a balance of 0.0.
