782582 divided by 90 
The aim is to understand the frequency of 90 in 782582.

Step 1:
7 divided by 90 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 90

Going ahead to step 2:
When dividing 78 by 90, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 90

Step 3:
782 divided by 90 is 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 720 from 782 to get 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 90

Let's proceed to step 4:
90 can be fit into 625 6 times, resulting in a remainder of 85.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 540 from 625 and we're left with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 90

Going ahead to step 5:
90 can be fit into 858 9 times, resulting in a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 869.0
Deduct 810 from 858 and we're left with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 90

Advancing to step 6:
90 can be fit into 482 5 times, resulting in a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 8695.0
Deduct 450 from 482 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 8695.3
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8695.35
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8695.355
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 8695.355 with a balance of 0.005.
