We're dividing 619074 by 72 
The aim is to understand the frequency of 72 in 619074.

Step 1:
6 divided by 72 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 72

Going ahead to step 2:
72 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 72

Let's proceed to step 3:
72 goes into 619 8 times with a remainder of 43.
The next digit of our result is 8. 
Result so far: 8.0
If we take 576 away from 619, we end up with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 72

On to step 4:
72 can be fit into 430 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 360 from 430 and we're left with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 72

On to step 5:
The number 72 fits into 707 9 times, leaving a remainder of 59.
The next digit of our result is 9. 
Result so far: 859.0
Subtract 648 from 707 to get 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 72

Step 6:
The number 72 fits into 594 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8598.0
Subtracting 576 from 594 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 72, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 8598.2
The remainder is 36 after subtracting 144 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
When dividing 360 by 72, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8598.25
Subtract 360 from 360 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 72, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8598.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 72, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8598.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8598.25 and a remainder of 0.0.
