393846 ÷ 1 
We're looking to find how many times 1 goes into 393846.

Let's proceed to step 1:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Step 2:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Let's proceed to step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 393.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3938.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Moving on to step 5:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 39384.0
Subtract 4 from 4 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Let's proceed to step 6:
6 divided by 1 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 393846.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 393846.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 393846.0
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.

After the division, we end up with 393846.0 and a remainder of 0.0.
