65421350 divided by 324 
The aim is to understand the frequency of 324 in 65421350.

Let's proceed to step 1:
6 divided by 324 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 324

Advancing to step 2:
324 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 324

Going ahead to step 3:
324 can be fit into 654 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 648 from 654 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 324

On to step 4:
When dividing 62 by 324, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 62, we end up with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 324

Advancing to step 5:
If we divide 621 by 324, we get 1 and a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we subtract 324 from 621, we get 297.
Grab the next digit (3) from the dividend, add it to 297, then carry on: 2973 / 324

On to step 6:
When dividing 2973 by 324, we get 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 2019.0
If we subtract 2916 from 2973, we get 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 324

Moving on to step 7:
324 goes into 575 1 times with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 20191.0
Deduct 324 from 575 and we're left with 251.
Take the next digit (0) from the dividend and append it to 251, then repeat: 2510 / 324

Going ahead to step 8:
2510 divided by 324 is 7 with a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 201917.0
The remainder is 242 after subtracting 2268 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 9:
The number 324 fits into 2420 7 times, leaving a remainder of 152.
Use 7 as the next digit of our solution. 
Result so far: 201917.7
Subtract 2268 from 2420 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 10:
If we divide 1520 by 324, we get 4 and a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 201917.74
Deduct 1296 from 1520 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
2240 divided by 324 is 6 with a remainder of 296.
The next digit of our result is 6. 
Result so far: 201917.746
Subtracting 1944 from 2240 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 12:
When dividing 2960 by 324, we get 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 201917.7469
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.

On to step 13:
When dividing 440 by 324, we get 1 with a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 201917.74691
The remainder is 116 after subtracting 324 from 440.
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 14:
324 goes into 1160 3 times with a remainder of 188.
The next digit of our result is 3. 
Result so far: 201917.746913
The remainder is 188 after subtracting 972 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 15:
1880 divided by 324 is 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 201917.7469135
If we take 1620 away from 1880, we end up with 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 16:
324 goes into 2600 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 201917.74691358
Subtract 2592 from 2600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 201917.74691358 with a balance of 8e-09.
