We're dividing 301806 by 1 
The aim is to understand the frequency of 1 in 301806.

On to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

On to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 3:
1 goes into 1 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 301.0
Subtracting 1 from 1 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 4:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 3018.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 5:
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: 30180.0
Subtract 0 from 0 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 6:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 301806.0
Subtracting 6 from 6 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.

Moving on to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 301806.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 301806.0
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 301806.0 with a remaining 0.0.
