We're dividing 40410 by 30 
Let's see how many times 30 fits into 40410.

On to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Let's proceed to step 2:
When dividing 40 by 30, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 30 from 40, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 30

On to step 3:
If we divide 104 by 30, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 14 after subtracting 90 from 104.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 30

Moving on to step 4:
30 can be fit into 141 4 times, resulting in a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtract 120 from 141 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 30

On to step 5:
30 goes into 210 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1347.0
If we subtract 210 from 210, 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 6:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1347.0
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.

Moving on to step 7:
30 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1347.0
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.

The final result is 1347.0 with a remainder of 0.0.
