We want to divide 2578446 by 804.

Moving on to step 1:
The number 804 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 804

Step 2:
When dividing 25 by 804, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 804

Let's proceed to step 3:
The number 804 fits into 257 0 times, leaving a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 257 after subtracting 0 from 257.
Bring next digit (8) of the dividend behind the 257 and repeat the process: 2578 / 804

Going ahead to step 4:
When dividing 2578 by 804, we get 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2412 away from 2578, we end up with 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 804

On to step 5:
804 goes into 1664 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 1608 from 1664, we get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 804

Moving on to step 6:
804 goes into 564 0 times with a remainder of 564.
Use 0 as the next digit of our solution. 
Result so far: 320.0
If we take 0 away from 564, we end up with 564.
Bring next digit (6) of the dividend behind the 564 and repeat the process: 5646 / 804

Going ahead to step 7:
804 can be fit into 5646 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 3207.0
The remainder is 18 after subtracting 5628 from 5646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
804 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 3207.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 9:
The number 804 fits into 1800 2 times, leaving a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 3207.02
Subtract 1608 from 1800 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
804 goes into 1920 2 times with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 3207.022
The remainder is 312 after subtracting 1608 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 3207.022 with a remaining 0.0312.
