We look at the division of 669222 by 1 
The aim is to understand the frequency of 1 in 669222.

On to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Moving on to step 3:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 669.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Step 4:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 6692.0
Subtract 2 from 2 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 5:
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: 66922.0
If we subtract 2 from 2, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 669222.0
Deduct 2 from 2 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 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 669222.0
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.

Going ahead to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 669222.0
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 quotient of the division is 669222.0, and the remainder is 0.0.
