78043 ÷ 72 
The aim is to understand the frequency of 72 in 78043.

Advancing to step 1:
72 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 72

Advancing to step 2:
If we divide 78 by 72, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 72 from 78, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 72

Advancing to step 3:
60 divided by 72 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 60 leaves us with 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 72

Step 4:
The number 72 fits into 604 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 576 from 604 leaves us with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 72

Advancing to step 5:
The number 72 fits into 283 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
If we take 216 away from 283, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 6:
72 goes into 670 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1083.9
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 72, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1083.93
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
72 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1083.93
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.

Step 9:
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: 1083.9305
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 72 is 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1083.93055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 1083.93055, with a leftover of 4e-05.
