353468 divided by 72 
The aim is to understand the frequency of 72 in 353468.

Moving on to step 1:
If we divide 3 by 72, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 72

Advancing to step 2:
The number 72 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 72

On to step 3:
When dividing 353 by 72, we get 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 288 from 353 leaves us with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 72

Advancing to step 4:
If we divide 654 by 72, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 6 after subtracting 648 from 654.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 72

Going ahead to step 5:
72 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
If we subtract 0 from 66, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 72

Going ahead to step 6:
If we divide 668 by 72, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 4909.0
Subtract 648 from 668 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 72, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 4909.2
Subtracting 144 from 200 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
The number 72 fits into 560 7 times, leaving a remainder of 56.
The next digit of our result is 7. 
Result so far: 4909.27
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
If we divide 560 by 72, we get 7 and a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 4909.277
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 4909.277 with a remainder of 0.0056.
