We're dividing 460099 by 90 
The aim is to understand the frequency of 90 in 460099.

Going ahead to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 90

Advancing to step 2:
When dividing 46 by 90, we get 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 90

Advancing 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 take 450 away from 460, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 90

Advancing to step 4:
100 divided by 90 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 90 away from 100, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 90

Step 5:
If we divide 109 by 90, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 511.0
Subtracting 90 from 109 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 90

Going ahead to step 6:
When dividing 199 by 90, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 5112.0
If we subtract 180 from 199, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
When dividing 190 by 90, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 5112.2
If we subtract 180 from 190, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 5112.21
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 5112.211
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 5112.211 with a balance of 0.001.
