We look at the division of 301123 by 10 
The aim is to understand the frequency of 10 in 301123.

Advancing to step 1:
10 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 10

Step 2:
The number 10 fits into 30 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 10

Moving on to step 3:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 10

On to step 4:
The number 10 fits into 11 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
If we subtract 10 from 11, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 10

Advancing to step 5:
10 goes into 12 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3011.0
If we take 10 away from 12, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 10

Advancing to step 6:
When dividing 23 by 10, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 30112.0
The remainder is 3 after subtracting 20 from 23.
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.
Record the quotient 3 as the next digit in the result. 
Result so far: 30112.3
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.

Advancing to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30112.3
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.

Let's proceed to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30112.3
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.

The final result is 30112.3 with a remainder of 0.0.
