We look at the division of 436520 by 30 
We want to figure out the number of times 436520 can be divided by 30.

Going ahead to step 1:
4 divided by 30 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 30

Moving on to step 2:
30 can be fit into 43 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 30

Going ahead to step 3:
When dividing 136 by 30, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 120 from 136 to get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 30

Let's proceed to step 4:
30 can be fit into 165 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 145.0
The remainder is 15 after subtracting 150 from 165.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 30

On to step 5:
If we divide 152 by 30, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 1455.0
The remainder is 2 after subtracting 150 from 152.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 30

On to step 6:
When dividing 20 by 30, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 14550.0
If we subtract 0 from 20, 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 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 14550.6
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.

Advancing to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14550.66
Subtracting 180 from 200 leaves us 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.

The final result is 14550.66 with a remainder of 0.02.
