522351 ÷ 1 
The aim is to understand the frequency of 1 in 522351.

Moving on to step 1:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Going ahead to step 2:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Moving on to step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 522.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 4:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 5223.0
If we subtract 3 from 3, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 5:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 52235.0
Subtract 5 from 5 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Let's proceed to step 6:
When dividing 1 by 1, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 522351.0
Subtract 1 from 1 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 522351.0
Deduct 0 from 0 and we're left 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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 522351.0
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.

The quotient of the division is 522351.0, and the remainder is 0.0.
