We look at the division of 287258 by 85 
We're looking to find how many times 85 goes into 287258.

Advancing to step 1:
If we divide 2 by 85, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 85

On to step 2:
85 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 85

Moving on to step 3:
287 divided by 85 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 255 away from 287, we end up with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 85

Advancing to step 4:
85 can be fit into 322 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 67 after subtracting 255 from 322.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 85

Advancing to step 5:
85 can be fit into 675 7 times, resulting in a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
If we take 595 away from 675, we end up with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 85

Moving on to step 6:
85 goes into 808 9 times with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 3379.0
Subtracting 765 from 808 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
The number 85 fits into 430 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3379.5
Deduct 425 from 430 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.

Step 8:
When dividing 50 by 85, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3379.5
If we subtract 0 from 50, we 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 9:
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: 3379.505
If we take 425 away from 500, we end up 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.

Let's proceed to step 10:
When dividing 750 by 85, we get 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 3379.5058
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.

Let's proceed to step 11:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 3379.50588
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.

The final result is 3379.50588 with a remainder of 2e-05.
