353060 divided by 90 
The aim is to understand the frequency of 90 in 353060.

Let's proceed to step 1:
90 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 90

Step 2:
When dividing 35 by 90, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 90

Going ahead to step 3:
90 goes into 353 3 times with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 270 from 353, we get 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 90

Advancing to step 4:
830 divided by 90 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 810 away from 830, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 90

Going ahead to step 5:
90 goes into 206 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 392.0
Deduct 180 from 206 and we're left with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 90

Moving on to step 6:
260 divided by 90 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 3922.0
Subtracting 180 from 260 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
800 divided by 90 is 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 3922.8
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 3922.88
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 3922.88 with a balance of 0.08.
