We look at the division of 819045 by 10 
The aim is to understand the frequency of 10 in 819045.

Let's proceed to step 1:
The number 10 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 10

Going ahead to step 2:
When dividing 81 by 10, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 80 from 81 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 10

Going ahead to step 3:
When dividing 19 by 10, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 10 from 19 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 10

Advancing to step 4:
When dividing 90 by 10, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 10

Moving on to step 5:
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: 8190.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 10

Advancing to step 6:
10 goes into 45 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 81904.0
Subtract 40 from 45 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
10 goes into 50 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 81904.5
The remainder is 0 after subtracting 50 from 50.
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 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 81904.5
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.

Let's proceed to step 9:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81904.5
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.

After the division, we end up with 81904.5 and a remainder of 0.0.
