We divide 100705 by 72
The aim is to understand the frequency of 72 in 100705.

Step 1:
1 divided by 72 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 72

Step 2:
When dividing 10 by 72, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 72

Going ahead to step 3:
72 can be fit into 100 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 72 from 100 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 72

Going ahead to step 4:
If we divide 287 by 72, we get 3 and a remainder of 71.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 216 from 287 leaves us with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 72

Advancing to step 5:
If we divide 710 by 72, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 648 from 710 leaves us with 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 72

Moving on to step 6:
625 divided by 72 is 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 1398.0
Subtracting 576 from 625 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
72 can be fit into 490 6 times, resulting in a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 1398.6
If we take 432 away from 490, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
580 divided by 72 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1398.68
If we subtract 576 from 580, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
72 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1398.68
Subtract 0 from 40 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.

Advancing to step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 1398.6805
Subtracting 360 from 400 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 11:
400 divided by 72 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1398.68055
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.

After the division, we end up with 1398.68055 and a remainder of 4e-05.
