Let's divide 294338 by 90
The aim is to understand the frequency of 90 in 294338.

Step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 90

On to step 2:
29 divided by 90 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 90

On to step 3:
90 can be fit into 294 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 270 from 294 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 90

Moving on to step 4:
If we divide 243 by 90, we get 2 and a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 180 from 243, we get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 90

Going ahead to step 5:
When dividing 633 by 90, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 327.0
The remainder is 3 after subtracting 630 from 633.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 90

Let's proceed to step 6:
90 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 3270.0
Subtract 0 from 38 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
When dividing 380 by 90, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3270.4
Subtracting 360 from 380 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 3270.42
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 3270.422
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3270.422 with a remaining 0.002.
