371443 ÷ 30 
We want to divide 371443 by 30.

Let's proceed to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

Advancing to step 2:
30 goes into 37 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 37 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 30

Going ahead to step 3:
If we divide 71 by 30, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 60 from 71 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 30

Advancing to step 4:
When dividing 114 by 30, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 90 from 114 leaves us with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 30

Going ahead to step 5:
30 goes into 244 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
If we take 240 away from 244, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 30

Moving on to step 6:
43 divided by 30 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 12381.0
If we take 30 away from 43, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
30 can be fit into 130 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 12381.4
If we subtract 120 from 130, 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.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 12381.43
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.

Moving on to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 12381.433
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.

The final outcome is 12381.433, with a leftover of 0.001.
