353339 ÷ 72 
The aim is to understand the frequency of 72 in 353339.

Advancing to step 1:
3 divided by 72 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 72

Let's proceed to step 2:
72 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 72

Advancing to step 3:
When dividing 353 by 72, we get 4 with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 288 from 353 to get 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 72

Step 4:
653 divided by 72 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 648 from 653 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 72

Moving on to step 5:
72 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 490.0
If we take 0 away from 53, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 72

Moving on to step 6:
The number 72 fits into 539 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 4907.0
Deduct 504 from 539 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
72 goes into 350 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 4907.4
The remainder is 62 after subtracting 288 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
72 can be fit into 620 8 times, resulting in a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 4907.48
Subtract 576 from 620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
72 goes into 440 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 4907.486
If we subtract 432 from 440, we 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.

Advancing 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: 4907.4861
Deduct 72 from 80 and we're left 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.

Moving on to step 11:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 4907.48611
If we take 72 away from 80, we end up 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 4907.48611 and a remainder of 8e-06.
