Let's divide 733490 by 1
The aim is to understand the frequency of 1 in 733490.

Advancing to step 1:
When dividing 7 by 1, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Moving on to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 733.0
If we take 3 away from 3, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 7334.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 73349.0
If we subtract 9 from 9, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 6:
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: 733490.0
If we take 0 away from 0, 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.

Going ahead to step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 733490.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 733490.0
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 final result is 733490.0 with a remainder of 0.0.
