Let's divide 668721 by 64
Let's see how many times 64 fits into 668721.

Advancing to step 1:
6 divided by 64 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 64

Moving on to step 2:
64 goes into 66 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 64 from 66.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 64

Let's proceed to step 3:
64 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 64

On to step 4:
64 goes into 287 4 times with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 256 from 287 and we're left with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 64

Going ahead to step 5:
When dividing 312 by 64, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
Subtracting 256 from 312 leaves us with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 64

Moving on to step 6:
The number 64 fits into 561 8 times, leaving a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 10448.0
Subtract 512 from 561 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
64 goes into 490 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 10448.7
Subtract 448 from 490 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 64 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 10448.76
Subtracting 384 from 420 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
If we divide 360 by 64, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 10448.765
Deduct 320 from 360 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 64 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10448.7656
If we take 384 away from 400, we end up 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.

Moving on to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10448.76562
If we take 128 away from 160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10448.765625
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.

Let's proceed to step 13:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10448.765625
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.

Going ahead to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10448.765625
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.

Our division results in 10448.765625 with a remaining 0.0.
