We're dividing 371730 by 30 
Let's see how many times 30 fits into 371730.

Advancing to step 1:
30 goes into 3 0 times 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.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 30

On to step 2:
30 can be fit into 37 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 30 from 37 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 30

Going ahead to step 3:
When dividing 71 by 30, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 60 from 71, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 30

Advancing to step 4:
When dividing 117 by 30, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 90 from 117, we get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 30

Moving on to step 5:
If we divide 273 by 30, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1239.0
The remainder is 3 after subtracting 270 from 273.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Advancing to step 6:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 12391.0
Subtract 30 from 30 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.

Let's proceed to step 7:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12391.0
If we take 0 away from 0, we end up 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.

Advancing to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12391.0
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.

After the division, we end up with 12391.0 and a remainder of 0.0.
