We divide 123940 by 10
The aim is to understand the frequency of 10 in 123940.

Moving on to step 1:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 10

Going ahead to step 2:
The number 10 fits into 12 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 10 from 12 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 10

On to step 3:
10 goes into 23 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 20 away from 23, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 10

Advancing to step 4:
39 divided by 10 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 30 away from 39, we end up with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 10

On to step 5:
When dividing 94 by 10, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 1239.0
If we subtract 90 from 94, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 10

Going ahead to step 6:
When dividing 40 by 10, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12394.0
If we subtract 40 from 40, 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.

Let's proceed to step 7:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12394.0
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.

On to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12394.0
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.

In conclusion, the division gives 12394.0 with a balance of 0.0.
