Let's divide 670186 by 30
We're looking to find how many times 30 goes into 670186.

Going ahead to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 30

Advancing to step 2:
The number 30 fits into 67 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 60 from 67 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 30

Step 3:
The number 30 fits into 70 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 60 from 70 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 30

Advancing to step 4:
30 can be fit into 101 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
If we take 90 away from 101, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 30

On to step 5:
When dividing 118 by 30, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 2233.0
Subtracting 90 from 118 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 30

On to step 6:
If we divide 286 by 30, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 22339.0
The remainder is 16 after subtracting 270 from 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 30 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 22339.5
Subtract 150 from 160 to 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.

Let's proceed to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 22339.53
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.

Let's proceed to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 22339.533
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.

Our division results in 22339.533 with a remaining 0.001.
