We divide 460392 by 90
The aim is to understand the frequency of 90 in 460392.

Step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 90

Let's proceed to step 2:
90 goes into 46 0 times with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 90

On to step 3:
When dividing 460 by 90, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 450 from 460, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 90

Advancing to step 4:
If we divide 103 by 90, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 13 after subtracting 90 from 103.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 90

Moving on to step 5:
90 can be fit into 139 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 511.0
Subtract 90 from 139 to get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 90

Step 6:
90 goes into 492 5 times with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 5115.0
The remainder is 42 after subtracting 450 from 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 90 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 5115.4
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 5115.46
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 5115.466
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 5115.466, with a leftover of 0.006.
