We look at the division of 358643 by 2 
Let's see how many times 2 fits into 358643.

Advancing to step 1:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Let's proceed to step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 1 after subtracting 14 from 15.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Moving on to step 3:
If we divide 18 by 2, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 179.0
Subtracting 18 from 18 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Going ahead to step 4:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 1793.0
If we subtract 6 from 6, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Going ahead to step 5:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 17932.0
Subtract 4 from 4 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Let's proceed to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 179321.0
If we subtract 2 from 3, 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:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 179321.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 179321.5
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.

Going ahead to step 9:
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: 179321.5
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.

Our division results in 179321.5 with a remaining 0.0.
