We look at the division of 396570 by 2 
We want to figure out the number of times 396570 can be divided by 2.

On to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Advancing to step 2:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 18 from 19 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Step 3:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 198.0
If we take 16 away from 16, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Going ahead 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: 1982.0
If we take 4 away from 5, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Going ahead to step 5:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 19828.0
If we take 16 away from 17, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Let's proceed to step 6:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 198285.0
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.

Going ahead to step 7:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 198285.0
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.

Moving on to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 198285.0
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.

The final outcome is 198285.0, with a leftover of 0.0.
