491328 divided by 1 
The aim is to understand the frequency of 1 in 491328.

Let's proceed to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 2:
9 divided by 1 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 9 from 9, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 3:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 491.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Going ahead to step 4:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4913.0
If we take 3 away from 3, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 5:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 49132.0
If we subtract 2 from 2, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 491328.0
If we take 8 away from 8, 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 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: 491328.0
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.

Moving on to step 8:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 491328.0
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.

The final outcome is 491328.0, with a leftover of 0.0.
