We look at the division of 339168 by 1 
The aim is to understand the frequency of 1 in 339168.

Going ahead to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 339.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Advancing to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 3391.0
If we take 1 away from 1, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Step 5:
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: 33916.0
If we take 6 away from 6, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 6:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 339168.0
Subtracting 8 from 8 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.

Step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 339168.0
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.

Step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 339168.0
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.

The final result is 339168.0 with a remainder of 0.0.
