664578 ÷ 65 
Let's see how many times 65 fits into 664578.

On to step 1:
65 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 65

Moving on to step 2:
If we divide 66 by 65, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 65 from 66, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 65

On to step 3:
65 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 14, we end up with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 65

Going ahead to step 4:
65 can be fit into 145 2 times, resulting in a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we take 130 away from 145, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 65

On to step 5:
If we divide 157 by 65, we get 2 and a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 1022.0
If we take 130 away from 157, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 65

Let's proceed to step 6:
When dividing 278 by 65, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 10224.0
Deduct 260 from 278 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
If we divide 180 by 65, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 10224.2
Deduct 130 from 180 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
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: 10224.27
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
65 goes into 450 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 10224.276
The remainder is 60 after subtracting 390 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 65, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 10224.2769
If we take 585 away from 600, we end up 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.

On to step 11:
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: 10224.27692
Subtract 130 from 150 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
65 can be fit into 200 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 10224.276923
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
When dividing 50 by 65, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10224.276923
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
65 can be fit into 500 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 10224.27692307
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 10224.27692307 with a remainder of 4.5e-08.
