We're dividing 216936 by 1 
The aim is to understand the frequency of 1 in 216936.

Step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Going ahead to step 2:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 1 from 1, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 216.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Advancing to step 4:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2169.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 21693.0
Subtract 3 from 3 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Going ahead to step 6:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 216936.0
Subtract 6 from 6 to 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 216936.0
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.

On to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 216936.0
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 216936.0 with a balance of 0.0.
