87820342 ÷ 321 
We're looking to find how many times 321 goes into 87820342.

Moving on to step 1:
The number 321 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 321

Advancing to step 2:
The number 321 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 321

Moving on to step 3:
321 goes into 878 2 times with a remainder of 236.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 642 from 878, we get 236.
Include the next digit (2) from the dividend after 236, then repeat: 2362 / 321

Advancing to step 4:
321 goes into 2362 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 2247 from 2362, we get 115.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 321

Let's proceed to step 5:
When dividing 1150 by 321, we get 3 with a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 273.0
If we subtract 963 from 1150, we get 187.
Take the next digit (3) from the dividend and append it to 187, then repeat: 1873 / 321

Going ahead to step 6:
When dividing 1873 by 321, we get 5 with a remainder of 268.
Use 5 as the next digit of our solution. 
Result so far: 2735.0
Subtracting 1605 from 1873 leaves us with 268.
Fetch the next digit (4) from the dividend, attach it to 268 and continue: 2684 / 321

Step 7:
The number 321 fits into 2684 8 times, leaving a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 27358.0
Subtracting 2568 from 2684 leaves us with 116.
Grab the next digit (2) from the dividend, add it to 116, then carry on: 1162 / 321

On to step 8:
The number 321 fits into 1162 3 times, leaving a remainder of 199.
Record the quotient 3 as the next digit in the result. 
Result so far: 273583.0
Deduct 963 from 1162 and we're left 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.

Let's proceed to step 9:
321 can be fit into 1990 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 273583.6
Subtract 1926 from 1990 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.

Advancing to step 10:
321 can be fit into 640 1 times, resulting in a remainder of 319.
The next digit of our result is 1. 
Result so far: 273583.61
The remainder is 319 after subtracting 321 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 11:
321 can be fit into 3190 9 times, resulting in a remainder of 301.
Put 9 as the next digit of the answer. 
Result so far: 273583.619
If we subtract 2889 from 3190, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
If we divide 3010 by 321, we get 9 and a remainder of 121.
The next digit of our result is 9. 
Result so far: 273583.6199
The remainder is 121 after subtracting 2889 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Our division results in 273583.6199 with a remaining 0.00121.
