We divide 78185274 by 324
The aim is to understand the frequency of 324 in 78185274.

On to step 1:
When dividing 7 by 324, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 324

Moving on to step 2:
78 divided by 324 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 324

Advancing to step 3:
781 divided by 324 is 2 with a remainder of 133.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 133 after subtracting 648 from 781.
Take the next digit (8) from the dividend and append it to 133, then repeat: 1338 / 324

Moving on to step 4:
324 goes into 1338 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 1296 from 1338, we get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 324

Moving on to step 5:
425 divided by 324 is 1 with a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtracting 324 from 425 leaves us with 101.
Include the next digit (2) from the dividend after 101, then repeat: 1012 / 324

Advancing to step 6:
324 goes into 1012 3 times with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 2413.0
Subtract 972 from 1012 to get 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 324

On to step 7:
If we divide 407 by 324, we get 1 and a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 24131.0
Subtract 324 from 407 to get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 324

Step 8:
The number 324 fits into 834 2 times, leaving a remainder of 186.
The number 2 becomes the next digit in our result. 
Result so far: 241312.0
Deduct 648 from 834 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
1860 divided by 324 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 241312.5
Subtracting 1620 from 1860 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
When dividing 2400 by 324, we get 7 with a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 241312.57
Deduct 2268 from 2400 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 11:
324 goes into 1320 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 241312.574
The remainder is 24 after subtracting 1296 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
324 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 241312.574
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
The number 324 fits into 2400 7 times, leaving a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 241312.57407
Subtract 2268 from 2400 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 14:
324 can be fit into 1320 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 241312.574074
Deduct 1296 from 1320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
The number 324 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 241312.574074
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
The number 324 fits into 2400 7 times, leaving a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 241312.57407407
If we subtract 2268 from 2400, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 241312.57407407 with a remaining 1.32e-07.
