286542 ÷ 1 
The aim is to understand the frequency of 1 in 286542.

Let's proceed to step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Step 2:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 8 from 8 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Step 3:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we take 6 away from 6, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2865.0
The remainder is 0 after subtracting 5 from 5.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Advancing to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 28654.0
If we take 4 away from 4, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 286542.0
The remainder is 0 after subtracting 2 from 2.
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:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 286542.0
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.

Step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 286542.0
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.

The final outcome is 286542.0, with a leftover of 0.0.
