We look at the division of 169225 by 10 
The aim is to understand the frequency of 10 in 169225.

Let's proceed to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 10

Step 2:
The number 10 fits into 16 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 10 away from 16, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 10

Moving on to step 3:
When dividing 69 by 10, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 60 from 69 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 10

Moving on to step 4:
92 divided by 10 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 90 from 92, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 10

Moving on to step 5:
10 can be fit into 22 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1692.0
The remainder is 2 after subtracting 20 from 22.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 10

Advancing to step 6:
10 can be fit into 25 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 16922.0
If we subtract 20 from 25, we 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.

On to step 7:
When dividing 50 by 10, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16922.5
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.

Going ahead to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16922.5
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.

Going ahead to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16922.5
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.

Our division results in 16922.5 with a remaining 0.0.
