338727 ÷ 1 
The aim is to understand the frequency of 1 in 338727.

Step 1:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 3 from 3 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 338.0
If we take 8 away from 8, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Moving on to step 4:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 3387.0
Subtract 7 from 7 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Step 5:
When dividing 2 by 1, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 33872.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 6:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 338727.0
Subtract 7 from 7 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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 338727.0
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:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 338727.0
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.

The final outcome is 338727.0, with a leftover of 0.0.
