52673831 divided by 324 
The aim is to understand the frequency of 324 in 52673831.

Advancing to step 1:
5 divided by 324 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 324

Advancing to step 2:
When dividing 52 by 324, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 324

Moving on to step 3:
The number 324 fits into 526 1 times, leaving a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 324 away from 526, we end up with 202.
Bring next digit (7) of the dividend behind the 202 and repeat the process: 2027 / 324

Moving on to step 4:
324 goes into 2027 6 times with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 1944 from 2027 leaves us with 83.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 324

Advancing to step 5:
If we divide 833 by 324, we get 2 and a remainder of 185.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtracting 648 from 833 leaves us with 185.
Fetch the next digit (8) from the dividend, attach it to 185 and continue: 1858 / 324

Let's proceed to step 6:
If we divide 1858 by 324, we get 5 and a remainder of 238.
Write down 5 as next digit of the result. 
Result so far: 1625.0
The remainder is 238 after subtracting 1620 from 1858.
Grab the next digit (3) from the dividend, add it to 238, then carry on: 2383 / 324

Let's proceed to step 7:
If we divide 2383 by 324, we get 7 and a remainder of 115.
The next digit of our result is 7. 
Result so far: 16257.0
If we take 2268 away from 2383, we end up with 115.
Append the next digit (1) from the dividend to 115 and continue with: 1151 / 324

Going ahead to step 8:
324 goes into 1151 3 times with a remainder of 179.
Put 3 as the next digit of the answer. 
Result so far: 162573.0
Subtract 972 from 1151 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
If we divide 1790 by 324, we get 5 and a remainder of 170.
The next digit of our result is 5. 
Result so far: 162573.5
If we take 1620 away from 1790, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
324 can be fit into 1700 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 162573.55
Subtract 1620 from 1700 to 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.

The final outcome is 162573.55, with a leftover of 0.08.
