We look at the division of 30660292 by 312 
We're looking to find how many times 312 goes into 30660292.

Let's proceed to step 1:
312 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 312

Advancing to step 2:
30 divided by 312 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 312

On to step 3:
When dividing 306 by 312, we get 0 with a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 306 after subtracting 0 from 306.
Grab the next digit (6) from the dividend, add it to 306, then carry on: 3066 / 312

Moving on to step 4:
If we divide 3066 by 312, we get 9 and a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 2808 away from 3066, we end up with 258.
Append the next digit (0) from the dividend to 258 and continue with: 2580 / 312

Step 5:
The number 312 fits into 2580 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 2496 from 2580, we get 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 312

Let's proceed to step 6:
When dividing 842 by 312, we get 2 with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 982.0
If we subtract 624 from 842, we get 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 312

Let's proceed to step 7:
312 goes into 2189 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 9827.0
If we take 2184 away from 2189, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 312

Going ahead to step 8:
312 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 98270.0
If we take 0 away from 52, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
If we divide 520 by 312, we get 1 and a remainder of 208.
The next digit of our result is 1. 
Result so far: 98270.1
If we subtract 312 from 520, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
When dividing 2080 by 312, we get 6 with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 98270.16
If we take 1872 away from 2080, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
When dividing 2080 by 312, we get 6 with a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 98270.166
Subtract 1872 from 2080 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 98270.166 with a remainder of 0.0208.
