We look at the division of 349220 by 1 
The aim is to understand the frequency of 1 in 349220.

Step 1:
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: 3.0
If we subtract 3 from 3, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 349.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Let's proceed to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3492.0
Subtract 2 from 2 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Advancing to step 5:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 34922.0
If we subtract 2 from 2, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Step 6:
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: 349220.0
If we take 0 away from 0, we end up 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:
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: 349220.0
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.

Step 8:
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: 349220.0
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.

The final result is 349220.0 with a remainder of 0.0.
