We divide 644276 by 10
The aim is to understand the frequency of 10 in 644276.

Let's proceed to step 1:
6 divided by 10 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 10

Going ahead to step 2:
The number 10 fits into 64 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 60 from 64, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 10

Going ahead to step 3:
When dividing 44 by 10, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 40 from 44 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 10

Step 4:
When dividing 42 by 10, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 644.0
If we take 40 away from 42, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 10

Moving on to step 5:
10 can be fit into 27 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 6442.0
Deduct 20 from 27 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 10

Let's proceed to step 6:
76 divided by 10 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 64427.0
If we take 70 away from 76, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
10 can be fit into 60 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 64427.6
If we subtract 60 from 60, 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 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64427.6
Subtract 0 from 0 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 9:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64427.6
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.

The quotient of the division is 64427.6, and the remainder is 0.0.
