We look at the division of 232123 by 10 
The aim is to understand the frequency of 10 in 232123.

Going ahead to step 1:
If we divide 2 by 10, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 10

Let's proceed to step 2:
If we divide 23 by 10, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 20 from 23 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 10

Step 3:
10 goes into 32 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 2 after subtracting 30 from 32.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

Advancing to step 4:
When dividing 21 by 10, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 232.0
If we subtract 20 from 21, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 10

Step 5:
10 can be fit into 12 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 2321.0
If we take 10 away from 12, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 10

Going ahead to step 6:
If we divide 23 by 10, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 23212.0
Deduct 20 from 23 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 10 fits into 30 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 23212.3
Subtracting 30 from 30 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.

On to step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23212.3
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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23212.3
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.

The final outcome is 23212.3, with a leftover of 0.0.
