We're dividing 45237 by 30 
Our goal is to divide 45237 by 30.

Moving on to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 30

Going ahead to step 2:
30 goes into 45 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 30 away from 45, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 30

Step 3:
30 goes into 152 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 150 away from 152, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 30

Advancing to step 4:
When dividing 23 by 30, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we take 0 away from 23, we end up with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 30

Let's proceed to step 5:
The number 30 fits into 237 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 1507.0
If we take 210 away from 237, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 6:
30 can be fit into 270 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 1507.9
Subtracting 270 from 270 leaves us with 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 7:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1507.9
Subtracting 0 from 0 leaves us with 0.
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 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1507.9
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.

After the division, we end up with 1507.9 and a remainder of 0.0.
