We're dividing 371149 by 30 
Let's see how many times 30 fits into 371149.

Going ahead to step 1:
3 divided by 30 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 30

On to step 2:
30 can be fit into 37 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 30 from 37 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 30

On to step 3:
The number 30 fits into 71 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 60 from 71 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 30

On to step 4:
111 divided by 30 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 90 from 111 leaves us with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 30

Let's proceed to step 5:
30 can be fit into 214 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 1237.0
Subtracting 210 from 214 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 30

Moving on to step 6:
30 can be fit into 49 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 12371.0
Subtract 30 from 49 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
30 goes into 190 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 12371.6
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 12371.63
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 12371.633
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.

Our division results in 12371.633 with a remaining 0.001.
