We look at the division of 321202 by 10 
The aim is to understand the frequency of 10 in 321202.

Moving on to step 1:
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: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 10

Going ahead to step 2:
The number 10 fits into 32 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 30 from 32 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 10

Let's proceed to step 3:
When dividing 21 by 10, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 20 from 21 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 10

Step 4:
10 goes into 12 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 321.0
Deduct 10 from 12 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 10

Moving on to step 5:
The number 10 fits into 20 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3212.0
Subtract 20 from 20 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 10

On to step 6:
If we divide 2 by 10, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 32120.0
Subtract 0 from 2 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 10, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 32120.2
If we subtract 20 from 20, 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.

On to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32120.2
Deduct 0 from 0 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.

Advancing to step 9:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32120.2
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.

After the division, we end up with 32120.2 and a remainder of 0.0.
