We're dividing 96304246 by 90 
The aim is to understand the frequency of 90 in 96304246.

Going ahead to step 1:
When dividing 9 by 90, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 90

Step 2:
The number 90 fits into 96 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 90 away from 96, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 90

Going ahead to step 3:
If we divide 63 by 90, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 90

Going ahead to step 4:
If we divide 630 by 90, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 630 from 630 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 90

Going ahead to step 5:
If we divide 4 by 90, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1070.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

Going ahead to step 6:
When dividing 42 by 90, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 10700.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 90

Going ahead to step 7:
90 goes into 424 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 107004.0
Subtract 360 from 424 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 90

Let's proceed to step 8:
If we divide 646 by 90, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1070047.0
Subtracting 630 from 646 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 90 is 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1070047.1
If we subtract 90 from 160, we get 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 10:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1070047.17
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 11:
If we divide 700 by 90, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1070047.177
Subtracting 630 from 700 leaves us 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 1070047.177 and a remainder of 0.007.
