278240 ÷ 85 
Let's see how many times 85 fits into 278240.

Let's proceed to step 1:
85 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 85

Going ahead to step 2:
85 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 85

Going ahead to step 3:
278 divided by 85 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 255 from 278 to get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 85

On to step 4:
85 can be fit into 232 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 170 from 232 leaves us with 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 85

Advancing to step 5:
When dividing 624 by 85, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 327.0
If we take 595 away from 624, we end up with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 85

Going ahead to step 6:
85 can be fit into 290 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3273.0
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 3273.4
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 3273.41
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 3273.411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 3273.411 with a remainder of 0.0065.
