We look at the division of 399119 by 30 
We want to figure out the number of times 399119 can be divided by 30.

Moving on to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 30

Let's proceed to step 2:
The number 30 fits into 39 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 30 away from 39, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 30

Step 3:
30 goes into 99 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 9 after subtracting 90 from 99.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 30

Step 4:
When dividing 91 by 30, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 90 from 91 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

Step 5:
30 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 1330.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 30

Going ahead to step 6:
When dividing 119 by 30, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 13303.0
Subtract 90 from 119 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 30, we get 9 and a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 13303.9
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 13303.96
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 13303.966
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 13303.966, with a leftover of 0.002.
