392803 ÷ 30 
Let's see how many times 30 fits into 392803.

Step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 30

Moving on to step 2:
30 can be fit into 39 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 39 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 30

Step 3:
30 can be fit into 92 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 90 from 92 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 30

Going ahead to step 4:
28 divided by 30 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 30

Going ahead to step 5:
30 goes into 280 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 1309.0
Deduct 270 from 280 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 30

On to step 6:
If we divide 103 by 30, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13093.0
Deduct 90 from 103 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 30 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 13093.4
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13093.43
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 30 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 13093.433
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 13093.433, and the remainder is 0.001.
