Let's divide 124398 by 30
We want to divide 124398 by 30.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 30

Let's proceed to step 2:
If we divide 12 by 30, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 30

Moving on to step 3:
The number 30 fits into 124 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 120 from 124 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 30

Step 4:
When dividing 43 by 30, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 30 from 43 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 30

On to step 5:
139 divided by 30 is 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 414.0
If we subtract 120 from 139, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 30

Step 6:
If we divide 198 by 30, we get 6 and a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 4146.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 30 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 4146.6
If we subtract 180 from 180, 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.

Step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4146.6
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.

Advancing to step 9:
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: 4146.6
The remainder is 0 after subtracting 0 from 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 4146.6 with a remainder of 0.0.
