We divide 450550 by 72
The aim is to understand the frequency of 72 in 450550.

Moving on to step 1:
72 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 72

Let's proceed to step 2:
The number 72 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 72

Advancing to step 3:
The number 72 fits into 450 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 432 from 450 to get 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 72

Step 4:
185 divided by 72 is 2 with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 62.0
The remainder is 41 after subtracting 144 from 185.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 72

Step 5:
72 can be fit into 415 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 625.0
Subtract 360 from 415 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 72

Let's proceed to step 6:
The number 72 fits into 550 7 times, leaving a remainder of 46.
The next digit of our result is 7. 
Result so far: 6257.0
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
If we divide 460 by 72, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 6257.6
Deduct 432 from 460 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 72 fits into 280 3 times, leaving a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 6257.63
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 6257.638
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 6257.6388
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 6257.6388 and a remainder of 0.00064.
