68678660 divided by 64 
We're looking to find how many times 64 goes into 68678660.

Step 1:
If we divide 6 by 64, we get 0 and 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.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 64

Moving on to step 2:
64 can be fit into 68 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 64 from 68 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 64

On to step 3:
When dividing 46 by 64, we get 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 46 after subtracting 0 from 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 64

Let's proceed to step 4:
64 goes into 467 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 19 after subtracting 448 from 467.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 64

Moving on to step 5:
64 goes into 198 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
If we subtract 192 from 198, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 64

Moving on to step 6:
66 divided by 64 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10731.0
Deduct 64 from 66 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 64

On to step 7:
When dividing 26 by 64, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 107310.0
Subtract 0 from 26 to get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 64

On to step 8:
The number 64 fits into 260 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1073104.0
The remainder is 4 after subtracting 256 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
64 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1073104.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 64 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1073104.06
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 1073104.062
Subtract 128 from 160 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.

Step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 1073104.0625
If we subtract 320 from 320, 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.

Step 13:
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: 1073104.0625
Subtracting 0 from 0 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.

Step 14:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1073104.0625
If we take 0 away from 0, we end up 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 1073104.0625 and a remainder of 0.0.
