662969 divided by 1 
The aim is to understand the frequency of 1 in 662969.

Advancing to step 1:
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: 6.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Moving on to step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 3:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 662.0
Subtracting 2 from 2 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 6629.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 66296.0
If we take 6 away from 6, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 662969.0
If we subtract 9 from 9, 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:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 662969.0
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.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 662969.0
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.

The final result is 662969.0 with a remainder of 0.0.
