We're dividing 103879 by 30 
We're looking to find how many times 30 goes into 103879.

Advancing to step 1:
The number 30 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 30

Let's proceed to step 2:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 30

Advancing to step 3:
When dividing 103 by 30, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 90 from 103, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 30

Step 4:
30 goes into 138 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 120 from 138 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 30

Let's proceed to step 5:
30 goes into 187 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 346.0
Subtract 180 from 187 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 30

Going ahead to step 6:
The number 30 fits into 79 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 3462.0
If we take 60 away from 79, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
30 goes into 190 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3462.6
Deduct 180 from 190 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.

Advancing to step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3462.63
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:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3462.633
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.

The final result is 3462.633 with a remainder of 0.001.
