We look at the division of 287321 by 85 
We want to figure out the number of times 287321 can be divided by 85.

Let's proceed to step 1:
2 divided by 85 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 85

Let's proceed to step 2:
85 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 85

Advancing to step 3:
When dividing 287 by 85, we get 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 255 from 287 to get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 85

Going ahead to step 4:
85 goes into 323 3 times with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 255 away from 323, we end up with 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 85

Step 5:
85 goes into 682 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 338.0
Subtracting 680 from 682 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 85

Step 6:
21 divided by 85 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 3380.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 85, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 3380.2
Subtract 170 from 210 to get 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 8:
When dividing 400 by 85, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 3380.24
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 85 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 3380.247
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 85, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3380.247
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 3380.24705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 3380.247058
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
700 divided by 85 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 3380.2470588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3380.2470588 and a remainder of 2e-07.
