393117 ÷ 30 
We want to figure out the number of times 393117 can be divided by 30.

Going ahead to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 30

On to step 2:
30 goes into 39 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 39 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 30

On to step 3:
If we divide 93 by 30, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 90 from 93 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 30

Going ahead to step 4:
31 divided by 30 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtracting 30 from 31 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

On to step 5:
The number 30 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 1310.0
If we subtract 0 from 11, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 30

Going ahead to step 6:
If we divide 117 by 30, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 13103.0
Subtracting 90 from 117 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
If we divide 270 by 30, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 13103.9
Subtract 270 from 270 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.

Let's proceed to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13103.9
Subtract 0 from 0 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.

Moving on to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13103.9
Subtract 0 from 0 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.

The final outcome is 13103.9, with a leftover of 0.0.
