We're dividing 370383 by 30 
Let's see how many times 30 fits into 370383.

Moving on to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 30

Moving on to step 2:
The number 30 fits into 37 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 37 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 30

Going ahead to step 3:
30 goes into 70 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 60 from 70 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 30

Going ahead to step 4:
If we divide 103 by 30, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 90 away from 103, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 30

Let's proceed to step 5:
When dividing 138 by 30, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
The remainder is 18 after subtracting 120 from 138.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 30

On to step 6:
30 goes into 183 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 12346.0
Deduct 180 from 183 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 30 fits into 30 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 12346.1
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12346.1
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.

Going ahead to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12346.1
Subtract 0 from 0 to 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.

The quotient of the division is 12346.1, and the remainder is 0.0.
