385569 divided by 1 
The aim is to understand the frequency of 1 in 385569.

Let's proceed to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 2:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 38.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Advancing to step 3:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 385.0
Deduct 5 from 5 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 4:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3855.0
Subtract 5 from 5 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 38556.0
Subtract 6 from 6 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

On to step 6:
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: 385569.0
Subtracting 9 from 9 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.

Moving on 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: 385569.0
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.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 385569.0
Subtract 0 from 0 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.

The final outcome is 385569.0, with a leftover of 0.0.
