Let's divide 199293 by 72
The aim is to understand the frequency of 72 in 199293.

Step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 72

Moving on to step 2:
72 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 72

Step 3:
If we divide 199 by 72, we get 2 and a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 144 from 199 and we're left with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 72

Advancing to step 4:
The number 72 fits into 552 7 times, leaving a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 48 after subtracting 504 from 552.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 72

Step 5:
When dividing 489 by 72, we get 6 with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 276.0
Subtracting 432 from 489 leaves us with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 72

Advancing to step 6:
573 divided by 72 is 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 2767.0
Subtracting 504 from 573 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 72, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 2767.9
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
If we divide 420 by 72, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 2767.95
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 2767.958
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
72 goes into 240 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 2767.9583
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
When dividing 240 by 72, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 2767.95833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2767.95833 with a remainder of 2.4e-05.
