403656 divided by 1 
The aim is to understand the frequency of 1 in 403656.

Advancing to step 1:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 2:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 0, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 4:
6 divided by 1 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 4036.0
Subtract 6 from 6 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 5:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40365.0
The remainder is 0 after subtracting 5 from 5.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 403656.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to 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: 403656.0
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: 403656.0
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.

The final outcome is 403656.0, with a leftover of 0.0.
