We're dividing 480505 by 72 
The aim is to understand the frequency of 72 in 480505.

On to step 1:
4 divided by 72 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 72

Let's proceed to step 2:
72 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 72

Advancing to step 3:
The number 72 fits into 480 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 432 away from 480, we end up with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 72

Let's proceed to step 4:
The number 72 fits into 485 6 times, leaving a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 432 away from 485, we end up with 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 72

Let's proceed to step 5:
72 goes into 530 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 667.0
If we subtract 504 from 530, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 72

Moving on to step 6:
72 goes into 265 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 6673.0
If we take 216 away from 265, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
The number 72 fits into 490 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 6673.6
If we subtract 432 from 490, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
72 can be fit into 580 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6673.68
If we take 576 away from 580, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6673.68
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
72 goes into 400 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 6673.6805
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 6673.68055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 6673.68055 and a remainder of 4e-05.
