We're dividing 50343 by 1 
The aim is to understand the frequency of 1 in 50343.

On to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Moving on to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 503.0
If we take 3 away from 3, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

On to step 4:
1 goes into 4 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 5034.0
If we take 4 away from 4, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Going ahead to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 50343.0
If we subtract 3 from 3, 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.

On to step 6:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50343.0
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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50343.0
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.

Our division results in 50343.0 with a remaining 0.0.
