We're dividing 720905 by 10 
The aim is to understand the frequency of 10 in 720905.

Let's proceed to step 1:
7 divided by 10 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 10

Let's proceed to step 2:
If we divide 72 by 10, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 70 from 72, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 10

Going ahead to step 3:
10 can be fit into 20 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 0 after subtracting 20 from 20.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 10

Moving on to step 4:
10 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 720.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 10

Let's proceed to step 5:
When dividing 90 by 10, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 7209.0
If we take 90 away from 90, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 10

Step 6:
10 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 72090.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
10 can be fit into 50 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 72090.5
If we subtract 50 from 50, 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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72090.5
If we take 0 away from 0, we end up 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.

On to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72090.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 72090.5 with a balance of 0.0.
