We look at the division of 445737 by 72 
The aim is to understand the frequency of 72 in 445737.

Going ahead to step 1:
4 divided by 72 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 72

On to step 2:
If we divide 44 by 72, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 72

Moving on to step 3:
72 goes into 445 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 432 from 445 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 72

On to step 4:
When dividing 137 by 72, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 72 from 137, we get 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 72

Let's proceed to step 5:
If we divide 653 by 72, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 619.0
Subtract 648 from 653 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 72

Going ahead to step 6:
72 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 6190.0
Subtracting 0 from 57 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
72 can be fit into 570 7 times, resulting in a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 6190.7
If we take 504 away from 570, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
72 can be fit into 660 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 6190.79
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 72, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 6190.791
If we take 72 away from 120, we end up 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.

Moving on to step 10:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 6190.7916
Subtracting 432 from 480 leaves us 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.

Step 11:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 6190.79166
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.

Our division results in 6190.79166 with a remaining 4.8e-05.
