We divide 151545 by 1
The aim is to understand the frequency of 1 in 151545.

Step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 5 from 5 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Moving on to step 3:
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: 151.0
If we subtract 1 from 1, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 4:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1515.0
Subtract 5 from 5 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Step 5:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 15154.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 151545.0
If we subtract 5 from 5, 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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 151545.0
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.

Advancing 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: 151545.0
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.

In conclusion, the division gives 151545.0 with a balance of 0.0.
