We look at the division of 57430 by 1 
The aim is to understand the frequency of 1 in 57430.

Let's proceed to step 1:
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: 5.0
Subtract 5 from 5 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Let's proceed to step 2:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 7 from 7 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

On to step 3:
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: 574.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

On to step 4:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 5743.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 57430.0
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.

Advancing to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 57430.0
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.

Step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57430.0
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 57430.0, and the remainder is 0.0.
