Let's divide 13812911 by 324
The aim is to understand the frequency of 324 in 13812911.

Going ahead to step 1:
324 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 324

Let's proceed 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 (8) from the dividend and append it to 13, then repeat: 138 / 324

Going ahead to step 3:
If we divide 138 by 324, we get 0 and a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 138 to get 138.
Grab the next digit (1) from the dividend, add it to 138, then carry on: 1381 / 324

Let's proceed to step 4:
If we divide 1381 by 324, we get 4 and a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1296 from 1381 and we're left with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 324

On to step 5:
If we divide 852 by 324, we get 2 and a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 648 away from 852, we end up with 204.
Take the next digit (9) from the dividend and append it to 204, then repeat: 2049 / 324

Advancing to step 6:
324 goes into 2049 6 times with a remainder of 105.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Subtract 1944 from 2049 to get 105.
Include the next digit (1) from the dividend after 105, then repeat: 1051 / 324

Going ahead to step 7:
The number 324 fits into 1051 3 times, leaving a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 4263.0
Subtracting 972 from 1051 leaves us with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 324

Let's proceed to step 8:
791 divided by 324 is 2 with a remainder of 143.
The next digit of our result is 2. 
Result so far: 42632.0
The remainder is 143 after subtracting 648 from 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
The number 324 fits into 1430 4 times, leaving a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 42632.4
If we subtract 1296 from 1430, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
1340 divided by 324 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 42632.44
Subtract 1296 from 1340 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.

The final outcome is 42632.44, with a leftover of 0.044.
