We're dividing 339188 by 1 
The aim is to understand the frequency of 1 in 339188.

On to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Advancing to step 2:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Let's proceed to step 3:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
If we take 9 away from 9, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 3391.0
Subtract 1 from 1 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Let's proceed to step 5:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 33918.0
Subtract 8 from 8 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 339188.0
Deduct 8 from 8 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 339188.0
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.

Moving on to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 339188.0
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.

Our division results in 339188.0 with a remaining 0.0.
