2942 ÷ 82 
We're looking to find how many times 82 goes into 2942.

Going ahead to step 1:
If we divide 2 by 82, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 82

Advancing to step 2:
82 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 82

Advancing to step 3:
If we divide 294 by 82, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 246 from 294 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 82

Advancing to step 4:
82 goes into 482 5 times with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 410 from 482 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 5:
The number 82 fits into 720 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 35.8
Subtracting 656 from 720 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 6:
82 goes into 640 7 times with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 35.87
If we take 574 away from 640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
82 goes into 660 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 35.878
Subtract 656 from 660 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 82, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 35.878
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 82 fits into 400 4 times, leaving a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 35.87804
If we take 328 away from 400, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
If we divide 720 by 82, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 35.878048
Subtract 656 from 720 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
The number 82 fits into 640 7 times, leaving a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 35.8780487
If we take 574 away from 640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
660 divided by 82 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 35.87804878
Subtract 656 from 660 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 35.87804878 and a remainder of 4e-09.
