We divide 320108 by 90
The aim is to understand the frequency of 90 in 320108.

Moving on to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 90

Step 2:
If we divide 32 by 90, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 90

Let's proceed to step 3:
90 goes into 320 3 times with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 50 after subtracting 270 from 320.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 90

Step 4:
The number 90 fits into 501 5 times, leaving a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 450 away from 501, we end up with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 90

Step 5:
510 divided by 90 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 355.0
Subtracting 450 from 510 leaves us with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 90

Let's proceed to step 6:
If we divide 608 by 90, we get 6 and a remainder of 68.
The next digit of our result is 6. 
Result so far: 3556.0
Deduct 540 from 608 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
90 can be fit into 680 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 3556.7
Deduct 630 from 680 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3556.75
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3556.755
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 3556.755 with a balance of 0.005.
