We look at the division of 80948303 by 72 
The aim is to understand the frequency of 72 in 80948303.

Going ahead to step 1:
72 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 72

On to step 2:
80 divided by 72 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 72 from 80.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 72

Going ahead to step 3:
When dividing 89 by 72, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 17 after subtracting 72 from 89.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 72

On to step 4:
If we divide 174 by 72, we get 2 and a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we subtract 144 from 174, we get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 72

Advancing to step 5:
If we divide 308 by 72, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
Subtracting 288 from 308 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 72

Advancing to step 6:
72 can be fit into 203 2 times, resulting in a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 11242.0
The remainder is 59 after subtracting 144 from 203.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 72

Let's proceed to step 7:
72 goes into 590 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 112428.0
Subtracting 576 from 590 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 72

On to step 8:
The number 72 fits into 143 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1124281.0
If we take 72 away from 143, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
710 divided by 72 is 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 1124281.9
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
620 divided by 72 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 1124281.98
Subtracting 576 from 620 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 11:
72 goes into 440 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1124281.986
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 72, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1124281.9861
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 72 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1124281.98611
The remainder is 8 after subtracting 72 from 80.
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 1124281.98611 with a remaining 8e-06.
