We look at the division of 473504 by 1 
The aim is to understand the frequency of 1 in 473504.

Advancing to step 1:
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: 4.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Advancing to step 2:
When dividing 7 by 1, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 7 from 7, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
If we subtract 3 from 3, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4735.0
Deduct 5 from 5 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 5:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47350.0
Subtract 0 from 0 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 473504.0
Subtract 4 from 4 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.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 473504.0
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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 473504.0
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.

In conclusion, the division gives 473504.0 with a balance of 0.0.
