201415 divided by 1 
The aim is to understand the frequency of 1 in 201415.

Going ahead to step 1:
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: 2.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Let's proceed to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Advancing to step 3:
1 goes into 1 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
If we subtract 1 from 1, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2014.0
If we take 4 away from 4, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 5:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 20141.0
If we take 1 away from 1, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Going ahead to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 201415.0
Deduct 5 from 5 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 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 201415.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 201415.0
The remainder is 0 after subtracting 0 from 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 201415.0 with a remaining 0.0.
