We look at the division of 43159805 by 30 
We're looking to find how many times 30 goes into 43159805.

Moving on to step 1:
4 divided by 30 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 30

Moving on to step 2:
If we divide 43 by 30, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 30

Let's proceed to step 3:
If we divide 131 by 30, we get 4 and a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 120 from 131, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 30

Step 4:
The number 30 fits into 115 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 143.0
If we subtract 90 from 115, we get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 30

Let's proceed to step 5:
The number 30 fits into 259 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 1438.0
The remainder is 19 after subtracting 240 from 259.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 30

Step 6:
30 can be fit into 198 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 14386.0
If we take 180 away from 198, we end up with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 30

Step 7:
180 divided by 30 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 143866.0
Subtract 180 from 180 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 30

Let's proceed to step 8:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 1438660.0
If we take 0 away from 5, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 30 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1438660.1
If we subtract 30 from 50, 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.

Let's proceed to step 10:
When dividing 200 by 30, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1438660.16
Deduct 180 from 200 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.

Advancing to step 11:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1438660.166
Deduct 180 from 200 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.

In conclusion, the division gives 1438660.166 with a balance of 0.002.
