41908180 ÷ 324 
The aim is to understand the frequency of 324 in 41908180.

On to step 1:
324 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 324

On to step 2:
When dividing 41 by 324, we get 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 324

Going ahead to step 3:
324 can be fit into 419 1 times, resulting in a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 324 from 419, we get 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 324

Advancing to step 4:
The number 324 fits into 950 2 times, leaving a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 648 from 950 and we're left with 302.
Append the next digit (8) from the dividend to 302 and continue with: 3028 / 324

On to step 5:
324 goes into 3028 9 times with a remainder of 112.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtracting 2916 from 3028 leaves us with 112.
Append the next digit (1) from the dividend to 112 and continue with: 1121 / 324

Step 6:
324 can be fit into 1121 3 times, resulting in a remainder of 149.
The next digit of our result is 3. 
Result so far: 1293.0
If we take 972 away from 1121, we end up with 149.
Bring next digit (8) of the dividend behind the 149 and repeat the process: 1498 / 324

Advancing to step 7:
If we divide 1498 by 324, we get 4 and a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 12934.0
The remainder is 202 after subtracting 1296 from 1498.
Grab the next digit (0) from the dividend, add it to 202, then carry on: 2020 / 324

Step 8:
If we divide 2020 by 324, we get 6 and a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 129346.0
The remainder is 76 after subtracting 1944 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
When dividing 760 by 324, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 129346.2
If we subtract 648 from 760, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 10:
If we divide 1120 by 324, we get 3 and a remainder of 148.
The next digit of our result is 3. 
Result so far: 129346.23
The remainder is 148 after subtracting 972 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
When dividing 1480 by 324, we get 4 with a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 129346.234
Deduct 1296 from 1480 and we're left with 184.
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 12:
When dividing 1840 by 324, we get 5 with a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 129346.2345
Deduct 1620 from 1840 and we're left 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.

Moving on to step 13:
When dividing 2200 by 324, we get 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 129346.23456
Subtracting 1944 from 2200 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
The number 324 fits into 2560 7 times, leaving a remainder of 292.
The number 7 becomes the next digit in our result. 
Result so far: 129346.234567
The remainder is 292 after subtracting 2268 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 15:
324 goes into 2920 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 129346.2345679
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.

Let's proceed to step 16:
324 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 129346.2345679
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 129346.2345679 with a remaining 4e-08.
