921865 divided by 1 
The aim is to understand the frequency of 1 in 921865.

Advancing to step 1:
If we divide 9 by 1, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

On to step 2:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 0 after subtracting 2 from 2.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Going ahead to step 3:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 921.0
If we take 1 away from 1, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Let's proceed to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 9218.0
If we take 8 away from 8, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Advancing to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 92186.0
Subtract 6 from 6 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

On to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 921865.0
Deduct 5 from 5 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 7:
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: 921865.0
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.

Let's proceed 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: 921865.0
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.

After the division, we end up with 921865.0 and a remainder of 0.0.
