294298 divided by 90 
The aim is to understand the frequency of 90 in 294298.

On to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 90

Moving 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
Deduct 0 from 29 and we're left with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 90

Let's proceed to step 3:
90 can be fit into 294 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 270 from 294 and we're left with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 90

On to step 4:
90 goes into 242 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 62 after subtracting 180 from 242.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 90

Advancing to step 5:
90 can be fit into 629 6 times, resulting in a remainder of 89.
Write down 6 as next digit of the result. 
Result so far: 326.0
Deduct 540 from 629 and we're left with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 90

Moving on to step 6:
When dividing 898 by 90, we get 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 3269.0
If we subtract 810 from 898, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 7:
90 can be fit into 880 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 3269.9
Deduct 810 from 880 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 3269.97
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 3269.977
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 3269.977 and a remainder of 0.007.
