We look at the division of 401443 by 30 
We want to divide 401443 by 30.

Step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 30

Step 2:
When dividing 40 by 30, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 40 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 30

Going ahead to step 3:
If we divide 101 by 30, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 90 from 101 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 30

On to step 4:
The number 30 fits into 114 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 90 from 114 leaves us with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 30

Moving on to step 5:
If we divide 244 by 30, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1338.0
Subtract 240 from 244 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Let's proceed to step 6:
When dividing 43 by 30, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 13381.0
The remainder is 13 after subtracting 30 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
30 goes into 130 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 13381.4
Subtracting 120 from 130 leaves us 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.

Going ahead to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 13381.43
Subtracting 90 from 100 leaves us 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.

Step 9:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13381.433
Deduct 90 from 100 and we're left 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.

The quotient of the division is 13381.433, and the remainder is 0.001.
