Let's divide 729839 by 72
The aim is to understand the frequency of 72 in 729839.

Step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 72

Let's proceed to step 2:
When dividing 72 by 72, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 72 from 72.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 72

On to step 3:
If we divide 9 by 72, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 72

Advancing to step 4:
If we divide 98 by 72, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 72 from 98 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 72

Moving on to step 5:
72 can be fit into 263 3 times, resulting in a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 1013.0
Subtracting 216 from 263 leaves us with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 72

On to step 6:
72 can be fit into 479 6 times, resulting in a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 10136.0
If we take 432 away from 479, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
72 goes into 470 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 10136.6
Deduct 432 from 470 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
380 divided by 72 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 10136.65
If we subtract 360 from 380, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 72, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 10136.652
If we take 144 away from 200, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
72 goes into 560 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 10136.6527
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 10136.65277
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 10136.65277 with a remaining 5.6e-05.
