Let's divide 905015 by 1
The aim is to understand the frequency of 1 in 905015.

Advancing to step 1:
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: 9.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 2:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 3:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 905.0
Subtract 5 from 5 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

On to step 4:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9050.0
If we subtract 0 from 0, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 90501.0
Subtract 1 from 1 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 6:
If we divide 5 by 1, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 905015.0
The remainder is 0 after subtracting 5 from 5.
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:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 905015.0
If we take 0 away from 0, we end up 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:
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: 905015.0
If we take 0 away from 0, we end up 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 quotient of the division is 905015.0, and the remainder is 0.0.
