Let's divide 339565 by 85
Let's see how many times 85 fits into 339565.

Going ahead to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 85

Going ahead to step 2:
The number 85 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 85

Step 3:
The number 85 fits into 339 3 times, leaving a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 255 from 339, we get 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 85

Advancing to step 4:
The number 85 fits into 845 9 times, leaving a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 765 away from 845, we end up with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 85

On to step 5:
The number 85 fits into 806 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 399.0
Subtracting 765 from 806 leaves us with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 85

Let's proceed to step 6:
85 can be fit into 415 4 times, resulting in a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 3994.0
Subtract 340 from 415 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
750 divided by 85 is 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 3994.8
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 8:
700 divided by 85 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 3994.88
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3994.88 with a remaining 0.02.
