We look at the division of 730148 by 72 
The aim is to understand the frequency of 72 in 730148.

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
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 72

Going ahead to step 2:
73 divided by 72 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 72

Going ahead to step 3:
10 divided by 72 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 10, we end up with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 72

On to step 4:
When dividing 101 by 72, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 72 from 101 and we're left with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 72

Going ahead to step 5:
When dividing 294 by 72, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1014.0
Subtract 288 from 294 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 72

Moving on to step 6:
72 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 10140.0
The remainder is 68 after subtracting 0 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
72 goes into 680 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 10140.9
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
The number 72 fits into 320 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 10140.94
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 72, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10140.944
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10140.944, and the remainder is 0.0032.
