415181 ÷ 1 
The aim is to understand the frequency of 1 in 415181.

Moving on to step 1:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Moving on to step 2:
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: 41.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

On to step 3:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 415.0
Subtracting 5 from 5 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Going ahead to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 4151.0
If we subtract 1 from 1, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Let's proceed to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 41518.0
If we subtract 8 from 8, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 6:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 415181.0
Deduct 1 from 1 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 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 415181.0
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.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 415181.0
If we subtract 0 from 0, we 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 415181.0 with a remainder of 0.0.
