We look at the division of 394391 by 1 
Our goal is to divide 394391 by 1.

Moving on to step 1:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
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

Moving on to step 2:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 3:
When dividing 4 by 1, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 394.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Advancing to step 4:
1 goes into 3 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3943.0
Subtract 3 from 3 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Going ahead to step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 39439.0
Subtract 9 from 9 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Advancing to step 6:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 394391.0
Subtract 1 from 1 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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 394391.0
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.

Let's proceed to step 8:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 394391.0
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.

In conclusion, the division gives 394391.0 with a balance of 0.0.
