We look at the division of 921027 by 1 
The aim is to understand the frequency of 1 in 921027.

Advancing to step 1:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 2:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 92.0
If we subtract 2 from 2, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 921.0
Subtract 1 from 1 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Going ahead to step 4:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9210.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 5:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 92102.0
If we subtract 2 from 2, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 6:
If we divide 7 by 1, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 921027.0
Deduct 7 from 7 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.

Advancing 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: 921027.0
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.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 921027.0
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 quotient of the division is 921027.0, and the remainder is 0.0.
