205639 ÷ 1 
The aim is to understand the frequency of 1 in 205639.

Step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 2 from 2 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 0 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 3:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 205.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Going ahead to step 4:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2056.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Advancing to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 20563.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Moving on to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 205639.0
Deduct 9 from 9 and we're left 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 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 205639.0
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.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 205639.0
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 quotient of the division is 205639.0, and the remainder is 0.0.
