Let's divide 3118910 by 30
Let's see how many times 30 fits into 3118910.

On to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 30

On to step 2:
If we divide 31 by 30, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 31 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

Let's proceed to step 3:
When dividing 11 by 30, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 30

On to step 4:
If we divide 118 by 30, we get 3 and a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtracting 90 from 118 leaves us with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 30

On to step 5:
289 divided by 30 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
Deduct 270 from 289 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 30

Step 6:
30 goes into 191 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 10396.0
Subtract 180 from 191 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 30

On to step 7:
When dividing 110 by 30, we get 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 103963.0
If we take 90 away from 110, 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.

Moving on to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 103963.6
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.

Step 9:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 103963.66
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 quotient of the division is 103963.66, and the remainder is 0.02.
