753758 ÷ 72 
The aim is to understand the frequency of 72 in 753758.

On to step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 72

Step 2:
If we divide 75 by 72, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 72 from 75 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 72

Moving on to step 3:
When dividing 33 by 72, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 72

Moving on to step 4:
72 can be fit into 337 4 times, resulting in a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 288 from 337 to get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 72

Going ahead to step 5:
When dividing 495 by 72, we get 6 with a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 1046.0
The remainder is 63 after subtracting 432 from 495.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 72

On to step 6:
The number 72 fits into 638 8 times, leaving a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 10468.0
Subtract 576 from 638 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
72 goes into 620 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 10468.8
The remainder is 44 after subtracting 576 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
72 can be fit into 440 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10468.86
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
72 goes into 80 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 10468.861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 72, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 10468.8611
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10468.8611 and a remainder of 8e-05.
