We divide 668386 by 64
We're looking to find how many times 64 goes into 668386.

Advancing to step 1:
64 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 64

Going ahead to step 2:
If we divide 66 by 64, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 64 from 66 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 64

On to step 3:
The number 64 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 64

Advancing to step 4:
When dividing 283 by 64, we get 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we subtract 256 from 283, we get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 64

Step 5:
64 can be fit into 278 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 1044.0
Subtract 256 from 278 to get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 64

Moving on to step 6:
The number 64 fits into 226 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 10443.0
If we take 192 away from 226, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 64 fits into 340 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10443.5
Subtract 320 from 340 to get 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 8:
200 divided by 64 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 10443.53
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 64, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 10443.531
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 64, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 10443.5312
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.

Going ahead to step 11:
If we divide 320 by 64, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10443.53125
Subtract 320 from 320 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.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10443.53125
The remainder is 0 after subtracting 0 from 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 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10443.53125
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.

In conclusion, the division gives 10443.53125 with a balance of 0.0.
