Let's divide 387199 by 30
We're looking to find how many times 30 goes into 387199.

Advancing to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 30

On to step 2:
38 divided by 30 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 30 from 38.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 30

On to step 3:
30 goes into 87 2 times with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 27 after subtracting 60 from 87.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 30

Step 4:
The number 30 fits into 271 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 270 away from 271, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 30

Advancing to step 5:
If we divide 19 by 30, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 1290.0
If we subtract 0 from 19, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 30

Let's proceed to step 6:
30 can be fit into 199 6 times, resulting in a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 12906.0
The remainder is 19 after subtracting 180 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 30, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 12906.6
Subtracting 180 from 190 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.

Moving on to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 12906.63
Deduct 90 from 100 and we're left 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.

Going ahead to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 12906.633
If we subtract 90 from 100, 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.

After the division, we end up with 12906.633 and a remainder of 0.001.
