Let's divide 38011 by 90
The aim is to understand the frequency of 90 in 38011.

Step 1:
90 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 90

On to step 2:
90 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 90

Let's proceed to step 3:
If we divide 380 by 90, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 360 from 380, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 90

Step 4:
201 divided by 90 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 180 from 201 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 90

Step 5:
The number 90 fits into 211 2 times, leaving a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
The remainder is 31 after subtracting 180 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 6:
If we divide 310 by 90, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 422.3
Subtracting 270 from 310 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 422.34
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 422.344
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 422.344 with a balance of 0.004.
