644384 ÷ 65 
Let's see how many times 65 fits into 644384.

Let's proceed to step 1:
65 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 65

Going ahead to step 2:
65 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 65

On to step 3:
When dividing 644 by 65, we get 9 with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 585 from 644 to get 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 65

Going ahead 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
Subtract 585 from 593 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 65

Advancing to step 5:
If we divide 88 by 65, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 991.0
The remainder is 23 after subtracting 65 from 88.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 65

Advancing to step 6:
234 divided by 65 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 9913.0
If we take 195 away from 234, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 65, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 9913.6
Deduct 390 from 390 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 65 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9913.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 65 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9913.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 9913.6 and a remainder of 0.0.
