We're dividing 31824319 by 72 
The aim is to understand the frequency of 72 in 31824319.

Advancing to step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 72

Advancing to step 2:
If we divide 31 by 72, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 72

Step 3:
When dividing 318 by 72, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 288 from 318 leaves us with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 72

Moving on to step 4:
If we divide 302 by 72, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 288 from 302 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 72

Moving on to step 5:
72 can be fit into 144 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 442.0
Subtracting 144 from 144 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 72

Going ahead to step 6:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 4420.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 72

Moving on to step 7:
72 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 44200.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 72

Going ahead to step 8:
When dividing 319 by 72, we get 4 with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 442004.0
If we subtract 288 from 319, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
When dividing 310 by 72, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 442004.4
The remainder is 22 after subtracting 288 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
220 divided by 72 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 442004.43
Subtract 216 from 220 to get 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 11:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 442004.43
Subtract 0 from 40 to 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.

Let's proceed to step 12:
When dividing 400 by 72, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 442004.4305
Subtract 360 from 400 to 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.

Moving on to step 13:
400 divided by 72 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 442004.43055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 442004.43055, with a leftover of 4e-05.
