39145711 divided by 324 
The aim is to understand the frequency of 324 in 39145711.

Moving on to step 1:
When dividing 3 by 324, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 324

Going ahead to step 2:
324 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 324

Advancing to step 3:
324 goes into 391 1 times with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 324 from 391, we get 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 324

Moving on to step 4:
674 divided by 324 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 26 after subtracting 648 from 674.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 324

Step 5:
265 divided by 324 is 0 with a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 265, we get 265.
Fetch the next digit (7) from the dividend, attach it to 265 and continue: 2657 / 324

Going ahead to step 6:
324 can be fit into 2657 8 times, resulting in a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 1208.0
Subtract 2592 from 2657 to get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 324

On to step 7:
651 divided by 324 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12082.0
If we subtract 648 from 651, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 324

Going ahead to step 8:
324 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 120820.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
If we divide 310 by 324, we get 0 and a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 120820.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
If we divide 3100 by 324, we get 9 and a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 120820.09
The remainder is 184 after subtracting 2916 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
324 goes into 1840 5 times with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 120820.095
Subtracting 1620 from 1840 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
The number 324 fits into 2200 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 120820.0956
If we subtract 1944 from 2200, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
324 can be fit into 2560 7 times, resulting in a remainder of 292.
Write down 7 as next digit of the result. 
Result so far: 120820.09567
If we take 2268 away from 2560, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 14:
324 can be fit into 2920 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 120820.095679
If we take 2916 away from 2920, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
324 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 120820.095679
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
400 divided by 324 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 120820.09567901
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 120820.09567901, with a leftover of 7.6e-08.
