We're dividing 1340429 by 324 
The aim is to understand the frequency of 324 in 1340429.

Let's proceed to step 1:
If we divide 1 by 324, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 324

Advancing to step 2:
324 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 324

On to step 3:
324 goes into 134 0 times with a remainder of 134.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 134 to get 134.
Append the next digit (0) from the dividend to 134 and continue with: 1340 / 324

Moving on to step 4:
324 goes into 1340 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1296 away from 1340, we end up with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 324

Advancing to step 5:
The number 324 fits into 444 1 times, leaving a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 324 from 444 to get 120.
Include the next digit (2) from the dividend after 120, then repeat: 1202 / 324

Step 6:
1202 divided by 324 is 3 with a remainder of 230.
Record the quotient 3 as the next digit in the result. 
Result so far: 413.0
If we subtract 972 from 1202, we get 230.
Include the next digit (9) from the dividend after 230, then repeat: 2309 / 324

Advancing to step 7:
324 can be fit into 2309 7 times, resulting in a remainder of 41.
The next digit of our result is 7. 
Result so far: 4137.0
Subtracting 2268 from 2309 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
324 can be fit into 410 1 times, resulting in a remainder of 86.
The next digit of our result is 1. 
Result so far: 4137.1
If we subtract 324 from 410, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
When dividing 860 by 324, we get 2 with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 4137.12
The remainder is 212 after subtracting 648 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 10:
324 goes into 2120 6 times with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 4137.126
Subtract 1944 from 2120 to 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 11:
If we divide 1760 by 324, we get 5 and a remainder of 140.
The next digit of our result is 5. 
Result so far: 4137.1265
If we subtract 1620 from 1760, we 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.

Step 12:
When dividing 1400 by 324, we get 4 with a remainder of 104.
The next digit of our result is 4. 
Result so far: 4137.12654
The remainder is 104 after subtracting 1296 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
When dividing 1040 by 324, we get 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 4137.126543
Subtracting 972 from 1040 leaves us 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.

Advancing to step 14:
When dividing 680 by 324, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 4137.1265432
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
If we divide 320 by 324, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 4137.1265432
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 4137.1265432 and a remainder of 3.2e-07.
