We're dividing 490552 by 1 
The aim is to understand the frequency of 1 in 490552.

Let's proceed to step 1:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

On to step 2:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 3:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
Subtract 0 from 0 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 4:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4905.0
Subtract 5 from 5 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Moving on to step 5:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 49055.0
Deduct 5 from 5 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Moving on to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 490552.0
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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 490552.0
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.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 490552.0
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.

In conclusion, the division gives 490552.0 with a balance of 0.0.
