12047815 ÷ 30 
Let's see how many times 30 fits into 12047815.

Moving on to step 1:
If we divide 1 by 30, we get 0 and 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 30

Let's proceed to step 2:
The number 30 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 30

Advancing to step 3:
When dividing 120 by 30, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 120 from 120, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 30

Let's proceed to step 4:
If we divide 4 by 30, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 30

Step 5:
47 divided by 30 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
If we subtract 30 from 47, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 30

Advancing to step 6:
30 can be fit into 178 5 times, resulting in a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 4015.0
Deduct 150 from 178 and we're left with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 30

Going ahead to step 7:
When dividing 281 by 30, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 40159.0
If we subtract 270 from 281, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 30

Step 8:
30 can be fit into 115 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 401593.0
The remainder is 25 after subtracting 90 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
30 can be fit into 250 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 401593.8
If we subtract 240 from 250, 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.

Going ahead to step 10:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 401593.83
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.

Moving on to step 11:
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: 401593.833
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.

The final result is 401593.833 with a remainder of 0.001.
