952425 divided by 90 
The aim is to understand the frequency of 90 in 952425.

Step 1:
9 divided by 90 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 90

Step 2:
The number 90 fits into 95 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 90 away from 95, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 90

Moving on to step 3:
52 divided by 90 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 52, we get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 90

Advancing to step 4:
When dividing 524 by 90, we get 5 with a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we subtract 450 from 524, we get 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 90

Advancing to step 5:
90 can be fit into 742 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1058.0
If we subtract 720 from 742, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 90

Going ahead to step 6:
225 divided by 90 is 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 10582.0
If we take 180 away from 225, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
450 divided by 90 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10582.5
The remainder is 0 after subtracting 450 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10582.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 90, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10582.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10582.5, with a leftover of 0.0.
