578840 divided by 65 
Let's see how many times 65 fits into 578840.

Moving on to step 1:
65 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 65

Advancing to step 2:
The number 65 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 65

Going ahead to step 3:
65 goes into 578 8 times with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 520 from 578 and we're left with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 65

Let's proceed to step 4:
588 divided by 65 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 585 from 588, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 65

Going ahead to step 5:
If we divide 34 by 65, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 65

Advancing to step 6:
When dividing 340 by 65, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8905.0
If we subtract 325 from 340, 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.

Advancing to step 7:
65 goes into 150 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8905.2
Deduct 130 from 150 and we're left 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.

Let's proceed to step 8:
The number 65 fits into 200 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 8905.23
Deduct 195 from 200 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.

Going ahead to step 9:
If we divide 50 by 65, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8905.23
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
65 can be fit into 500 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 8905.2307
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
65 goes into 450 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 8905.23076
Subtracting 390 from 450 leaves us 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.

Going ahead to step 12:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 8905.230769
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
When dividing 150 by 65, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 8905.2307692
If we take 130 away from 150, we end up 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.

Advancing to step 14:
200 divided by 65 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 8905.23076923
Deduct 195 from 200 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.

After the division, we end up with 8905.23076923 and a remainder of 5e-09.
