478409 ÷ 1 
The aim is to understand the frequency of 1 in 478409.

Moving on to step 1:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Going ahead to step 2:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 478.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Going ahead to step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4784.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
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: 47840.0
Subtract 0 from 0 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Moving on to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 478409.0
If we subtract 9 from 9, 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.

Let's proceed to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 478409.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 478409.0
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.

In conclusion, the division gives 478409.0 with a balance of 0.0.
