505034 ÷ 72 
The aim is to understand the frequency of 72 in 505034.

On to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 72

Let's proceed to step 2:
72 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 72

On to step 3:
If we divide 505 by 72, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 504 from 505, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 72

Advancing to step 4:
72 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 72

Let's proceed to step 5:
The number 72 fits into 103 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
The remainder is 31 after subtracting 72 from 103.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 72

Step 6:
314 divided by 72 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 7014.0
If we take 288 away from 314, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
The number 72 fits into 260 3 times, leaving a remainder of 44.
The next digit of our result is 3. 
Result so far: 7014.3
Subtracting 216 from 260 leaves us with 44.
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:
When dividing 440 by 72, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7014.36
Deduct 432 from 440 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 9:
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: 7014.361
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.

Going ahead to step 10:
When dividing 80 by 72, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7014.3611
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.

Our division results in 7014.3611 with a remaining 8e-05.
