509720 divided by 64 
We want to figure out the number of times 509720 can be divided by 64.

Let's proceed to step 1:
If we divide 5 by 64, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 64

Going ahead to step 2:
The number 64 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 64

On to step 3:
When dividing 509 by 64, we get 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 448 from 509, we get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 64

Step 4:
64 goes into 617 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 41 after subtracting 576 from 617.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 64

Going ahead to step 5:
If we divide 412 by 64, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 796.0
If we subtract 384 from 412, we get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 64

Let's proceed to step 6:
64 can be fit into 280 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7964.0
Deduct 256 from 280 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
64 can be fit into 240 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 7964.3
Deduct 192 from 240 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7964.37
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 7964.375
Subtracting 320 from 320 leaves us 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 10:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7964.375
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.

Going ahead to step 11:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7964.375
If we subtract 0 from 0, we 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.

After the division, we end up with 7964.375 and a remainder of 0.0.
