We look at the division of 87360705 by 321 
Let's see how many times 321 fits into 87360705.

On to step 1:
321 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 321

Going ahead to step 2:
If we divide 87 by 321, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 321

Advancing to step 3:
873 divided by 321 is 2 with a remainder of 231.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 642 from 873 leaves us with 231.
Fetch the next digit (6) from the dividend, attach it to 231 and continue: 2316 / 321

Moving on to step 4:
321 goes into 2316 7 times with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 2247 from 2316 leaves us with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 321

Let's proceed to step 5:
321 can be fit into 690 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 272.0
Subtract 642 from 690 to get 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 321

On to step 6:
If we divide 487 by 321, we get 1 and a remainder of 166.
The next digit of our result is 1. 
Result so far: 2721.0
If we subtract 321 from 487, we get 166.
Bring next digit (0) of the dividend behind the 166 and repeat the process: 1660 / 321

Going ahead to step 7:
When dividing 1660 by 321, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 27215.0
Subtracting 1605 from 1660 leaves us with 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 321

Going ahead to step 8:
The number 321 fits into 555 1 times, leaving a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 272151.0
Deduct 321 from 555 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
2340 divided by 321 is 7 with a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 272151.7
If we subtract 2247 from 2340, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 10:
930 divided by 321 is 2 with a remainder of 288.
Record the quotient 2 as the next digit in the result. 
Result so far: 272151.72
Subtract 642 from 930 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 11:
The number 321 fits into 2880 8 times, leaving a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 272151.728
Subtract 2568 from 2880 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 12:
3120 divided by 321 is 9 with a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 272151.7289
If we take 2889 away from 3120, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 13:
The number 321 fits into 2310 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 272151.72897
Subtracting 2247 from 2310 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 14:
The number 321 fits into 630 1 times, leaving a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 272151.728971
Subtract 321 from 630 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 15:
321 goes into 3090 9 times with a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 272151.7289719
Deduct 2889 from 3090 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 16:
When dividing 2010 by 321, we get 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 272151.72897196
Subtracting 1926 from 2010 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 272151.72897196 with a remaining 8.4e-08.
