Let's divide 435020 by 30
Let's see how many times 30 fits into 435020.

Advancing to step 1:
30 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Let's proceed 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
If we take 30 away from 43, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 30

On to step 3:
If we divide 135 by 30, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 120 from 135, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 30

Going ahead to step 4:
The number 30 fits into 150 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
The remainder is 0 after subtracting 150 from 150.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 30

On to step 5:
30 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1450.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 30

Step 6:
If we divide 20 by 30, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 14500.0
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.

Going ahead to step 7:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 14500.6
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.

On 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: 14500.66
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.

Our division results in 14500.66 with a remaining 0.02.
