We look at the division of 459003 by 10 
The aim is to understand the frequency of 10 in 459003.

On to step 1:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 10

Going ahead to step 2:
10 can be fit into 45 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 40 from 45 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 10

Step 3:
10 can be fit into 59 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 50 from 59 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 10

Advancing to step 4:
If we divide 90 by 10, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 459.0
Subtract 90 from 90 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 10

Advancing to step 5:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4590.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 10

On to step 6:
When dividing 3 by 10, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 45900.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 10 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 45900.3
Deduct 30 from 30 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.

Going ahead to 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: 45900.3
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.

Moving on to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45900.3
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 final result is 45900.3 with a remainder of 0.0.
