We look at the division of 125914 by 10 
The aim is to understand the frequency of 10 in 125914.

Going ahead to step 1:
If we divide 1 by 10, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 10

Going ahead to step 2:
10 goes into 12 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 10 from 12, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 10

Going ahead to step 3:
10 goes into 25 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 5 after subtracting 20 from 25.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 10

Step 4:
The number 10 fits into 59 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 50 from 59 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

Advancing to step 5:
10 can be fit into 91 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 1259.0
The remainder is 1 after subtracting 90 from 91.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 10

Step 6:
The number 10 fits into 14 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 12591.0
Subtracting 10 from 14 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 10 fits into 40 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 12591.4
Subtract 40 from 40 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.

Let's proceed to step 8:
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: 12591.4
If we take 0 away from 0, we end up 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.

Step 9:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12591.4
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.

The final result is 12591.4 with a remainder of 0.0.
