We look at the division of 308377 by 30 
Let's see how many times 30 fits into 308377.

Advancing to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 30

Let's proceed to step 2:
30 goes into 30 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 30 from 30, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 30

Going ahead to step 3:
30 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 30

Going ahead to step 4:
When dividing 83 by 30, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtracting 60 from 83 leaves us with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 30

Advancing to step 5:
30 can be fit into 237 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 1027.0
Deduct 210 from 237 and we're left with 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 30

Moving on to step 6:
30 can be fit into 277 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10279.0
If we take 270 away from 277, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 30 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 10279.2
The remainder is 10 after subtracting 60 from 70.
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 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 10279.23
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.

On to step 9:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 10279.233
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.

Our division results in 10279.233 with a remaining 0.001.
