We look at the division of 644324 by 65 
Our goal is to divide 644324 by 65.

Let's proceed to step 1:
When dividing 6 by 65, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 65

Moving on to step 2:
65 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 65

Advancing to step 3:
65 goes into 644 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 585 from 644 leaves us with 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 65

Advancing to step 4:
The number 65 fits into 593 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 585 away from 593, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 65

Going ahead to step 5:
When dividing 82 by 65, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 991.0
If we take 65 away from 82, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 65

Step 6:
65 goes into 174 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 9912.0
Subtract 130 from 174 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
440 divided by 65 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 9912.6
Subtracting 390 from 440 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.

Step 8:
500 divided by 65 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 9912.67
Subtracting 455 from 500 leaves us 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.

On to step 9:
The number 65 fits into 450 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 9912.676
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 65, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 9912.6769
If we subtract 585 from 600, 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 11:
When dividing 150 by 65, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 9912.67692
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.

Advancing to step 12:
65 goes into 200 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 9912.676923
If we subtract 195 from 200, we 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.

Moving on to step 13:
If we divide 50 by 65, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9912.676923
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
65 goes into 500 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 9912.67692307
The remainder is 45 after subtracting 455 from 500.
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 outcome is 9912.67692307, with a leftover of 4.5e-08.
