We look at the division of 492202 by 1 
The aim is to understand the frequency of 1 in 492202.

On to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 2:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 9 from 9, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 3:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
Subtract 2 from 2 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Step 4:
1 goes into 2 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 4922.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49220.0
If we subtract 0 from 0, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 492202.0
Deduct 2 from 2 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.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 492202.0
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.

Moving on to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 492202.0
If we subtract 0 from 0, 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.

The quotient of the division is 492202.0, and the remainder is 0.0.
