We're dividing 17591171 by 324 
The aim is to understand the frequency of 324 in 17591171.

Step 1:
1 divided by 324 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 324

On to step 2:
324 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 324

Step 3:
The number 324 fits into 175 0 times, leaving a remainder of 175.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 175, we end up with 175.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 324

Moving on to step 4:
When dividing 1759 by 324, we get 5 with a remainder of 139.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1620 from 1759 to get 139.
Grab the next digit (1) from the dividend, add it to 139, then carry on: 1391 / 324

Advancing to step 5:
When dividing 1391 by 324, we get 4 with a remainder of 95.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 1296 from 1391, we get 95.
Append the next digit (1) from the dividend to 95 and continue with: 951 / 324

Step 6:
324 goes into 951 2 times with a remainder of 303.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
The remainder is 303 after subtracting 648 from 951.
Grab the next digit (7) from the dividend, add it to 303, then carry on: 3037 / 324

Step 7:
324 can be fit into 3037 9 times, resulting in a remainder of 121.
The next digit of our result is 9. 
Result so far: 5429.0
Subtract 2916 from 3037 to get 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 324

Step 8:
The number 324 fits into 1211 3 times, leaving a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 54293.0
Subtract 972 from 1211 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
When dividing 2390 by 324, we get 7 with a remainder of 122.
The number 7 becomes the next digit in our result. 
Result so far: 54293.7
Subtract 2268 from 2390 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
When dividing 1220 by 324, we get 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 54293.73
If we take 972 away from 1220, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 11:
2480 divided by 324 is 7 with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 54293.737
The remainder is 212 after subtracting 2268 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 12:
When dividing 2120 by 324, we get 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 54293.7376
If we subtract 1944 from 2120, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
When dividing 1760 by 324, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 54293.73765
Subtract 1620 from 1760 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
324 goes into 1400 4 times with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 54293.737654
Subtracting 1296 from 1400 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 15:
The number 324 fits into 1040 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 54293.7376543
Deduct 972 from 1040 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 16:
680 divided by 324 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 54293.73765432
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 54293.73765432 with a remaining 3.2e-08.
