We look at the division of 152437 by 30 
We're looking to find how many times 30 goes into 152437.

Step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 30

Advancing to step 2:
The number 30 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 30

Let's proceed to step 3:
When dividing 152 by 30, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 150 from 152 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 30

Step 4:
The number 30 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtract 0 from 24 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 30

Let's proceed to step 5:
When dividing 243 by 30, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 508.0
Subtract 240 from 243 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 30

Let's proceed to step 6:
30 goes into 37 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 5081.0
If we take 30 away from 37, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
30 goes into 70 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 5081.2
If we take 60 away from 70, 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.

Moving on to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 5081.23
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 5081.233
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.

The final result is 5081.233 with a remainder of 0.001.
