25712 ÷ 324 
The aim is to understand the frequency of 324 in 25712.

On to step 1:
The number 324 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 324

Step 2:
The number 324 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 324

Let's proceed to step 3:
The number 324 fits into 257 0 times, leaving a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Grab the next digit (1) from the dividend, add it to 257, then carry on: 2571 / 324

On to step 4:
When dividing 2571 by 324, we get 7 with a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 2268 from 2571, we get 303.
Append the next digit (2) from the dividend to 303 and continue with: 3032 / 324

Moving on to step 5:
When dividing 3032 by 324, we get 9 with a remainder of 116.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 2916 from 3032 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 6:
If we divide 1160 by 324, we get 3 and a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 79.3
Subtracting 972 from 1160 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 7:
1880 divided by 324 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 79.35
If we subtract 1620 from 1880, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 8:
The number 324 fits into 2600 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 79.358
Subtracting 2592 from 2600 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 324, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 79.358
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
324 goes into 800 2 times with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 79.35802
If we take 648 away from 800, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 11:
324 can be fit into 1520 4 times, resulting in a remainder of 224.
The next digit of our result is 4. 
Result so far: 79.358024
Subtract 1296 from 1520 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
If we divide 2240 by 324, we get 6 and a remainder of 296.
Write down 6 as next digit of the result. 
Result so far: 79.3580246
The remainder is 296 after subtracting 1944 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 13:
2960 divided by 324 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 79.35802469
Subtract 2916 from 2960 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 79.35802469 with a remaining 4.4e-08.
