300725 divided by 1 
The aim is to understand the frequency of 1 in 300725.

Advancing to step 1:
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: 3.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 2:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 3:
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: 300.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Going ahead to step 4:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 3007.0
Subtracting 7 from 7 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 5:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 30072.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 300725.0
Subtracting 5 from 5 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:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 300725.0
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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 300725.0
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 outcome is 300725.0, with a leftover of 0.0.
