We divide 668930 by 64
We're looking to find how many times 64 goes into 668930.

On to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 64

Going ahead to step 2:
The number 64 fits into 66 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 64 from 66 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 64

Let's proceed to step 3:
64 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 28, we get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 64

Let's proceed to step 4:
64 can be fit into 289 4 times, resulting in a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we take 256 away from 289, we end up with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 64

Let's proceed to step 5:
The number 64 fits into 333 5 times, leaving a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
If we take 320 away from 333, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 64

On to step 6:
If we divide 130 by 64, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 10452.0
Subtract 128 from 130 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
64 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10452.0
Subtract 0 from 20 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.

On to step 8:
200 divided by 64 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 10452.03
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 10452.031
If we take 64 away from 80, 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.

Step 10:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10452.0312
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 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 10452.03125
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 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10452.03125
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.

On to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10452.03125
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.

The final outcome is 10452.03125, with a leftover of 0.0.
