We look at the division of 385392 by 1 
We want to divide 385392 by 1.

Moving on to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 3:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 385.0
Subtracting 5 from 5 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Advancing to step 4:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3853.0
Subtract 3 from 3 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Advancing to step 5:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 38539.0
Subtract 9 from 9 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 6:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 385392.0
Deduct 2 from 2 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 385392.0
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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 385392.0
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.

The quotient of the division is 385392.0, and the remainder is 0.0.
