We look at the division of 345509 by 10 
The aim is to understand the frequency of 10 in 345509.

Let's proceed to step 1:
10 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 10

Let's proceed to step 2:
10 can be fit into 34 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 4 after subtracting 30 from 34.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 10

Advancing to step 3:
When dividing 45 by 10, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 40 from 45 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 10

Step 4:
55 divided by 10 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 345.0
Subtract 50 from 55 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 10

Going ahead to step 5:
10 can be fit into 50 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3455.0
If we subtract 50 from 50, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 10

Going ahead to step 6:
10 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 34550.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 10 fits into 90 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 34550.9
The remainder is 0 after subtracting 90 from 90.
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 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34550.9
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.

Moving on to step 9:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34550.9
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.

Our division results in 34550.9 with a remaining 0.0.
