997339 divided by 72 
The aim is to understand the frequency of 72 in 997339.

Moving on to step 1:
9 divided by 72 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 72

On to step 2:
99 divided by 72 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 99 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 72

Going ahead to step 3:
277 divided by 72 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 61 after subtracting 216 from 277.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 72

Advancing to step 4:
When dividing 613 by 72, we get 8 with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 576 from 613 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 72

Step 5:
72 can be fit into 373 5 times, resulting in a remainder of 13.
The next digit of our result is 5. 
Result so far: 1385.0
Deduct 360 from 373 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 72

Advancing to step 6:
If we divide 139 by 72, we get 1 and a remainder of 67.
The next digit of our result is 1. 
Result so far: 13851.0
If we subtract 72 from 139, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 7:
The number 72 fits into 670 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 13851.9
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
72 can be fit into 220 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13851.93
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.

Let's proceed to step 9:
72 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13851.93
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 13851.9305
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.

Advancing to step 11:
When dividing 400 by 72, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 13851.93055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 13851.93055 with a remaining 4e-05.
