Let's divide 402154 by 10
The aim is to understand the frequency of 10 in 402154.

Let's proceed to step 1:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 10

Advancing to step 2:
The number 10 fits into 40 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 40 from 40, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 10

On to step 3:
10 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Going ahead to step 4:
21 divided by 10 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 10

Step 5:
When dividing 15 by 10, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 4021.0
Subtracting 10 from 15 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 10

Going ahead to step 6:
10 can be fit into 54 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 40215.0
If we subtract 50 from 54, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 10, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 40215.4
Subtracting 40 from 40 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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40215.4
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.

On to step 9:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40215.4
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.

After the division, we end up with 40215.4 and a remainder of 0.0.
