511956 divided by 1 
The aim is to understand the frequency of 1 in 511956.

Advancing to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

On to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 511.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 5119.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Step 5:
1 goes into 5 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 51195.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

On to step 6:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 511956.0
Deduct 6 from 6 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.

On to step 7:
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: 511956.0
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.

Let's proceed to step 8:
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: 511956.0
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.

After the division, we end up with 511956.0 and a remainder of 0.0.
