We look at the division of 124958 by 1 
The aim is to understand the frequency of 1 in 124958.

Moving on to step 1:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 2:
1 goes into 2 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 2 from 2, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 3:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 124.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 4:
1 goes into 9 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1249.0
If we subtract 9 from 9, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Going ahead to step 5:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12495.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Step 6:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 124958.0
If we take 8 away from 8, 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 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 124958.0
The remainder is 0 after subtracting 0 from 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 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: 124958.0
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 124958.0, with a leftover of 0.0.
