833343 ÷ 72 
The aim is to understand the frequency of 72 in 833343.

Step 1:
8 divided by 72 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 72

Advancing to step 2:
The number 72 fits into 83 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 83, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 72

Moving on to step 3:
72 can be fit into 113 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 41 after subtracting 72 from 113.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 72

Step 4:
The number 72 fits into 413 5 times, leaving a remainder of 53.
The next digit of our result is 5. 
Result so far: 115.0
Subtracting 360 from 413 leaves us with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 72

Moving on to step 5:
72 goes into 534 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 1157.0
Subtracting 504 from 534 leaves us with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 72

Step 6:
72 goes into 303 4 times with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 11574.0
Deduct 288 from 303 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 72 fits into 150 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 11574.2
If we take 144 away from 150, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
72 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11574.2
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
600 divided by 72 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 11574.208
Subtracting 576 from 600 leaves us 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.

Moving on to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 11574.2083
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 72, we get 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 11574.20833
If we take 216 away from 240, we end up 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.

After the division, we end up with 11574.20833 and a remainder of 2.4e-05.
