We divide 804826 by 90
The aim is to understand the frequency of 90 in 804826.

Advancing to step 1:
8 divided by 90 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 90

On to step 2:
90 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 90

Let's proceed to step 3:
804 divided by 90 is 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 720 from 804, we get 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 90

Advancing to step 4:
90 goes into 848 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 810 from 848, we get 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 90

Moving on to step 5:
90 can be fit into 382 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 894.0
The remainder is 22 after subtracting 360 from 382.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 90

Let's proceed to step 6:
If we divide 226 by 90, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 8942.0
If we take 180 away from 226, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
90 can be fit into 460 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8942.5
Subtracting 450 from 460 leaves us 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.

Let's proceed to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 8942.51
The remainder is 10 after subtracting 90 from 100.
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 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 8942.511
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.

In conclusion, the division gives 8942.511 with a balance of 0.001.
