We divide 854603 by 1
The aim is to understand the frequency of 1 in 854603.

Moving on to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Advancing to step 2:
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: 85.0
The remainder is 0 after subtracting 5 from 5.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Going ahead to step 3:
When dividing 4 by 1, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Let's proceed to step 4:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 8546.0
Subtract 6 from 6 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 5:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 85460.0
If we take 0 away from 0, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Let's proceed to step 6:
When dividing 3 by 1, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 854603.0
Subtracting 3 from 3 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:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 854603.0
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.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 854603.0
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 final result is 854603.0 with a remainder of 0.0.
