403343 divided by 1 
The aim is to understand the frequency of 1 in 403343.

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

Moving on to step 2:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

On to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 403.0
Subtract 3 from 3 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 4:
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: 4033.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Let's proceed to step 5:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 40334.0
If we subtract 4 from 4, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 403343.0
The remainder is 0 after subtracting 3 from 3.
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 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: 403343.0
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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 403343.0
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.

In conclusion, the division gives 403343.0 with a balance of 0.0.
