972231 ÷ 1 
The aim is to understand the frequency of 1 in 972231.

On to step 1:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Going ahead to step 2:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Advancing to step 3:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 972.0
If we take 2 away from 2, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 9722.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Moving on to step 5:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 97223.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

On to step 6:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 972231.0
If we subtract 1 from 1, 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.

Going ahead to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 972231.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 972231.0
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.

The quotient of the division is 972231.0, and the remainder is 0.0.
