We're dividing 45459 by 30 
We're looking to find how many times 30 goes into 45459.

Moving on 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
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 30

On to step 2:
The number 30 fits into 45 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 30 from 45, we get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 30

Let's proceed to step 3:
30 can be fit into 154 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 150 from 154 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 30

Advancing to step 4:
When dividing 45 by 30, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Subtract 30 from 45 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 30

Moving on to step 5:
When dividing 159 by 30, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 1515.0
The remainder is 9 after subtracting 150 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 6:
30 can be fit into 90 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 1515.3
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 30, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1515.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1515.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1515.3 with a remainder of 0.0.
