637728 divided by 64 
We want to figure out the number of times 637728 can be divided by 64.

Going ahead to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 64

Let's proceed to step 2:
63 divided by 64 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 64

Advancing to step 3:
The number 64 fits into 637 9 times, leaving a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 576 from 637 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 64

On to step 4:
64 goes into 617 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 576 from 617 and we're left with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 64

Let's proceed to step 5:
If we divide 412 by 64, we get 6 and a remainder of 28.
The next digit of our result is 6. 
Result so far: 996.0
The remainder is 28 after subtracting 384 from 412.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 64

Step 6:
The number 64 fits into 288 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 9964.0
Subtract 256 from 288 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
64 goes into 320 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9964.5
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 9964.5
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:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9964.5
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 9964.5 and a remainder of 0.0.
