We're dividing 897789 by 72 
The aim is to understand the frequency of 72 in 897789.

Let's proceed to step 1:
72 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 72

Going ahead to step 2:
72 goes into 89 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 72 from 89 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 72

Advancing to step 3:
If we divide 177 by 72, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 144 from 177 to get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 72

Step 4:
337 divided by 72 is 4 with a remainder of 49.
The next digit of our result is 4. 
Result so far: 124.0
Deduct 288 from 337 and we're left with 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 72

Let's proceed to step 5:
72 goes into 498 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 1246.0
If we subtract 432 from 498, we get 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 72

Let's proceed to step 6:
669 divided by 72 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 12469.0
Subtract 648 from 669 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 72, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 12469.2
Subtract 144 from 210 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
When dividing 660 by 72, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 12469.29
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 12469.291
Subtracting 72 from 120 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 10:
480 divided by 72 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 12469.2916
If we take 432 away from 480, 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.

Going ahead to step 11:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 12469.29166
The remainder is 48 after subtracting 432 from 480.
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 12469.29166 with a remaining 4.8e-05.
