We're dividing 488019 by 72 
The aim is to understand the frequency of 72 in 488019.

Advancing to step 1:
When dividing 4 by 72, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 72

On to step 2:
48 divided by 72 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 72

Moving on to step 3:
488 divided by 72 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 432 from 488 and we're left with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 72

Advancing to step 4:
If we divide 560 by 72, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 67.0
If we take 504 away from 560, we end up with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 72

Moving on to step 5:
If we divide 561 by 72, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 677.0
Subtracting 504 from 561 leaves us with 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 72

Advancing to step 6:
When dividing 579 by 72, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 6778.0
Subtracting 576 from 579 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 72 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6778.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 72 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 6778.04
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 6778.041
Deduct 72 from 120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 6778.0416
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6778.04166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 6778.04166, with a leftover of 4.8e-05.
