We divide 29002456 by 90
The aim is to understand the frequency of 90 in 29002456.

Moving on to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 90

Moving on to step 2:
90 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 90

Step 3:
90 goes into 290 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 270 from 290 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 90

Going ahead to step 4:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 180 from 200, we get 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 90

Moving on to step 5:
90 can be fit into 202 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 322.0
Subtracting 180 from 202 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 90

Going ahead to step 6:
When dividing 224 by 90, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 3222.0
If we subtract 180 from 224, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 90

Advancing to step 7:
If we divide 445 by 90, we get 4 and a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 32224.0
Deduct 360 from 445 and we're left with 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 90

Moving on to step 8:
90 goes into 856 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 322249.0
If we subtract 810 from 856, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
The number 90 fits into 460 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 322249.5
If we take 450 away from 460, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 322249.51
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 90 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 322249.511
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 322249.511 with a remaining 0.001.
