666773 ÷ 1 
The aim is to understand the frequency of 1 in 666773.

On to step 1:
6 divided by 1 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 2:
6 divided by 1 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 6 from 6 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Let's proceed to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Step 4:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 6667.0
If we take 7 away from 7, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 5:
7 divided by 1 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 66677.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Let's proceed to step 6:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 666773.0
Subtract 3 from 3 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 666773.0
Subtract 0 from 0 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.

Going ahead to step 8:
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: 666773.0
Subtract 0 from 0 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.

After the division, we end up with 666773.0 and a remainder of 0.0.
