Let's divide 97811523 by 324
The aim is to understand the frequency of 324 in 97811523.

Going ahead to step 1:
If we divide 9 by 324, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 324

Going ahead to step 2:
324 can be fit into 97 0 times, resulting in a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Take the next digit (8) from the dividend and append it to 97, then repeat: 978 / 324

On to step 3:
978 divided by 324 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 972 from 978 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 324

Let's proceed to step 4:
When dividing 61 by 324, we get 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 61 to get 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 324

Moving on to step 5:
324 can be fit into 611 1 times, resulting in a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
Subtract 324 from 611 to get 287.
Grab the next digit (5) from the dividend, add it to 287, then carry on: 2875 / 324

Going ahead to step 6:
324 can be fit into 2875 8 times, resulting in a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 3018.0
If we subtract 2592 from 2875, we get 283.
Include the next digit (2) from the dividend after 283, then repeat: 2832 / 324

Advancing to step 7:
2832 divided by 324 is 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 30188.0
The remainder is 240 after subtracting 2592 from 2832.
Bring next digit (3) of the dividend behind the 240 and repeat the process: 2403 / 324

Going ahead to step 8:
When dividing 2403 by 324, we get 7 with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 301887.0
Subtract 2268 from 2403 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
If we divide 1350 by 324, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 301887.4
Deduct 1296 from 1350 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
324 goes into 540 1 times with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 301887.41
Subtracting 324 from 540 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
324 can be fit into 2160 6 times, resulting in a remainder of 216.
The next digit of our result is 6. 
Result so far: 301887.416
Subtracting 1944 from 2160 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
324 goes into 2160 6 times with a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 301887.4166
Deduct 1944 from 2160 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 301887.4166, and the remainder is 0.00216.
