We divide 324996 by 90
The aim is to understand the frequency of 90 in 324996.

Let's proceed to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 90

Going ahead to step 2:
The number 90 fits into 32 0 times, leaving a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 90

Going ahead to step 3:
The number 90 fits into 324 3 times, leaving a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 270 from 324 to get 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 90

Step 4:
90 goes into 549 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 540 from 549, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 90

Advancing to step 5:
90 goes into 99 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 361.0
Deduct 90 from 99 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 90

Advancing to step 6:
96 divided by 90 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 3611.0
Deduct 90 from 96 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
90 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3611.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 3611.06
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 3611.066
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 3611.066, and the remainder is 0.006.
