120599 ÷ 1 
The aim is to understand the frequency of 1 in 120599.

Going ahead to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Let's proceed to step 2:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing 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: 1205.0
If we take 5 away from 5, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 5:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12059.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 120599.0
Subtract 9 from 9 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.

Step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 120599.0
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: 120599.0
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 result is 120599.0 with a remainder of 0.0.
