Let's divide 123308 by 30
We want to figure out the number of times 123308 can be divided by 30.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Step 2:
When dividing 12 by 30, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 30

Advancing to step 3:
If we divide 123 by 30, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 120 from 123.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 30

Advancing to step 4:
30 goes into 33 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 30 from 33 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 30

Moving on to step 5:
30 goes into 30 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 411.0
Deduct 30 from 30 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 30

Advancing to step 6:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 4110.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 30, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 4110.2
Deduct 60 from 80 and we're left 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.

Going ahead to step 8:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4110.26
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 4110.266
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4110.266, with a leftover of 0.002.
