526428 divided by 1 
The aim is to understand the frequency of 1 in 526428.

Advancing to step 1:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Step 2:
When dividing 2 by 1, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Advancing to step 3:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 526.0
If we subtract 6 from 6, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 5264.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 52642.0
If we subtract 2 from 2, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Let's proceed to step 6:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 526428.0
If we subtract 8 from 8, 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 526428.0
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.

Moving on to step 8:
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: 526428.0
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 result is 526428.0 with a remainder of 0.0.
