We divide 664412 by 10
We want to figure out the number of times 664412 can be divided by 10.

On to step 1:
When dividing 6 by 10, we get 0 with 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 10

Let's proceed to step 2:
10 goes into 66 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 60 from 66 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 10

Step 3:
64 divided by 10 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 66.0
Deduct 60 from 64 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 10

Let's proceed to step 4:
10 can be fit into 44 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 664.0
Subtracting 40 from 44 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 10

Advancing to step 5:
41 divided by 10 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 6644.0
Subtracting 40 from 41 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 10

Let's proceed to step 6:
When dividing 12 by 10, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 66441.0
If we take 10 away from 12, we end up with 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:
If we divide 20 by 10, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 66441.2
Subtract 20 from 20 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.

Let's proceed to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 66441.2
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.

Moving on to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66441.2
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.

The final result is 66441.2 with a remainder of 0.0.
