728204 divided by 1 
The aim is to understand the frequency of 1 in 728204.

On to step 1:
If we divide 7 by 1, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 7 from 7 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Step 2:
When dividing 2 by 1, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 728.0
Subtract 8 from 8 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 4:
When dividing 2 by 1, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 7282.0
If we take 2 away from 2, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Step 5:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72820.0
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

Going ahead to step 6:
When dividing 4 by 1, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 728204.0
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.
Use 0 as the next digit of our solution. 
Result so far: 728204.0
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.

Going ahead to 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: 728204.0
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.

After the division, we end up with 728204.0 and a remainder of 0.0.
