107878 ÷ 30 
Let's see how many times 30 fits into 107878.

Let's proceed to step 1:
1 divided by 30 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 30

Step 2:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 30

On to step 3:
30 goes into 107 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 17 after subtracting 90 from 107.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 30

On to step 4:
30 goes into 178 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 150 from 178 to get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 30

Step 5:
The number 30 fits into 287 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 359.0
Subtract 270 from 287 to get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 30

Step 6:
When dividing 178 by 30, we get 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 3595.0
The remainder is 28 after subtracting 150 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
If we divide 280 by 30, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 3595.9
Subtract 270 from 280 to 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.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 3595.93
If we take 90 away from 100, we end up 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:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3595.933
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.

Our division results in 3595.933 with a remaining 0.001.
