258698 ÷ 1 
The aim is to understand the frequency of 1 in 258698.

Going ahead to step 1:
When dividing 2 by 1, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 2 from 2 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 2:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25.0
If we take 5 away from 5, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 3:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 258.0
If we take 8 away from 8, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 4:
When dividing 6 by 1, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2586.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 5:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 25869.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Going ahead to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 258698.0
Subtract 8 from 8 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.

On to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 258698.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 258698.0
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 final outcome is 258698.0, with a leftover of 0.0.
