82420489 ÷ 855 
We want to figure out the number of times 82420489 can be divided by 855.

On to step 1:
8 divided by 855 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 855

On to step 2:
855 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 855

On to step 3:
855 goes into 824 0 times with a remainder of 824.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 824, we end up with 824.
Append the next digit (2) from the dividend to 824 and continue with: 8242 / 855

Let's proceed to step 4:
If we divide 8242 by 855, we get 9 and a remainder of 547.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 547 after subtracting 7695 from 8242.
Fetch the next digit (0) from the dividend, attach it to 547 and continue: 5470 / 855

Let's proceed to step 5:
855 goes into 5470 6 times with a remainder of 340.
The next digit of our result is 6. 
Result so far: 96.0
Deduct 5130 from 5470 and we're left with 340.
Take the next digit (4) from the dividend and append it to 340, then repeat: 3404 / 855

Moving on to step 6:
855 goes into 3404 3 times with a remainder of 839.
Put 3 as the next digit of the answer. 
Result so far: 963.0
If we subtract 2565 from 3404, we get 839.
Fetch the next digit (8) from the dividend, attach it to 839 and continue: 8398 / 855

Step 7:
When dividing 8398 by 855, we get 9 with a remainder of 703.
Put 9 as the next digit of the answer. 
Result so far: 9639.0
If we take 7695 away from 8398, we end up with 703.
Take the next digit (9) from the dividend and append it to 703, then repeat: 7039 / 855

Going ahead to step 8:
If we divide 7039 by 855, we get 8 and a remainder of 199.
The number 8 becomes the next digit in our result. 
Result so far: 96398.0
Subtracting 6840 from 7039 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
855 can be fit into 1990 2 times, resulting in a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 96398.2
Subtracting 1710 from 1990 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
The number 855 fits into 2800 3 times, leaving a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 96398.23
If we subtract 2565 from 2800, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 11:
2350 divided by 855 is 2 with a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 96398.232
Deduct 1710 from 2350 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 12:
855 goes into 6400 7 times with a remainder of 415.
Write down 7 as next digit of the result. 
Result so far: 96398.2327
Subtract 5985 from 6400 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 13:
If we divide 4150 by 855, we get 4 and a remainder of 730.
Put 4 as the next digit of the answer. 
Result so far: 96398.23274
If we take 3420 away from 4150, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 14:
The number 855 fits into 7300 8 times, leaving a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 96398.232748
Deduct 6840 from 7300 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 15:
4600 divided by 855 is 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 96398.2327485
Subtracting 4275 from 4600 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 16:
855 goes into 3250 3 times with a remainder of 685.
The number 3 becomes the next digit in our result. 
Result so far: 96398.23274853
The remainder is 685 after subtracting 2565 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

The final outcome is 96398.23274853, with a leftover of 6.85e-07.
