Let's divide 906407 by 1
The aim is to understand the frequency of 1 in 906407.

Advancing to step 1:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 9 from 9 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 906.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 4:
4 divided by 1 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 9064.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 5:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90640.0
Subtract 0 from 0 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

On to step 6:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 906407.0
If we take 7 away from 7, we end up 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.

Moving on to step 7:
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: 906407.0
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.

Going ahead to step 8:
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: 906407.0
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 906407.0, and the remainder is 0.0.
