We divide 716404 by 1
The aim is to understand the frequency of 1 in 716404.

Advancing to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 2:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we subtract 1 from 1, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 3:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 716.0
If we take 6 away from 6, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

On to step 4:
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: 7164.0
Subtract 4 from 4 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 5:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71640.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 716404.0
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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 716404.0
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:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 716404.0
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.

The quotient of the division is 716404.0, and the remainder is 0.0.
