Let's divide 80066912 by 331
Let's see how many times 331 fits into 80066912.

Step 1:
331 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 331

Step 2:
331 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 331

Going ahead to step 3:
331 goes into 800 2 times with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 662 from 800 to get 138.
Take the next digit (6) from the dividend and append it to 138, then repeat: 1386 / 331

Moving on to step 4:
The number 331 fits into 1386 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 62 after subtracting 1324 from 1386.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 331

Advancing to step 5:
626 divided by 331 is 1 with a remainder of 295.
Put 1 as the next digit of the answer. 
Result so far: 241.0
If we subtract 331 from 626, we get 295.
Include the next digit (9) from the dividend after 295, then repeat: 2959 / 331

Going ahead to step 6:
The number 331 fits into 2959 8 times, leaving a remainder of 311.
Put 8 as the next digit of the answer. 
Result so far: 2418.0
If we subtract 2648 from 2959, we get 311.
Fetch the next digit (1) from the dividend, attach it to 311 and continue: 3111 / 331

On to step 7:
331 can be fit into 3111 9 times, resulting in a remainder of 132.
The number 9 becomes the next digit in our result. 
Result so far: 24189.0
Subtract 2979 from 3111 to get 132.
Fetch the next digit (2) from the dividend, attach it to 132 and continue: 1322 / 331

Advancing to step 8:
331 goes into 1322 3 times with a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 241893.0
Deduct 993 from 1322 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
3290 divided by 331 is 9 with a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 241893.9
The remainder is 311 after subtracting 2979 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 10:
The number 331 fits into 3110 9 times, leaving a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 241893.99
If we take 2979 away from 3110, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

After the division, we end up with 241893.99 and a remainder of 0.131.
