We're dividing 42156105 by 82 
Let's see how many times 82 fits into 42156105.

On to step 1:
If we divide 4 by 82, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 82

On to step 2:
82 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 82

Advancing to step 3:
82 goes into 421 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 410 from 421, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 82

Going ahead to step 4:
The number 82 fits into 115 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 82 away from 115, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 82

Step 5:
336 divided by 82 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
The remainder is 8 after subtracting 328 from 336.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 82

Going ahead to step 6:
When dividing 81 by 82, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 5140.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 82

On to step 7:
If we divide 810 by 82, we get 9 and a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 51409.0
Deduct 738 from 810 and we're left with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 82

Advancing to step 8:
The number 82 fits into 725 8 times, leaving a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 514098.0
If we subtract 656 from 725, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
When dividing 690 by 82, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 514098.8
Subtract 656 from 690 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 82 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 514098.84
Subtracting 328 from 340 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
82 goes into 120 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 514098.841
The remainder is 38 after subtracting 82 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
The number 82 fits into 380 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 514098.8414
Subtracting 328 from 380 leaves us 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.

On to step 13:
If we divide 520 by 82, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 514098.84146
Subtract 492 from 520 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
When dividing 280 by 82, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 514098.841463
If we subtract 246 from 280, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
82 goes into 340 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 514098.8414634
Subtract 328 from 340 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
The number 82 fits into 120 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 514098.84146341
Subtract 82 from 120 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 514098.84146341 and a remainder of 3.8e-08.
