Let's divide 123825 by 72
The aim is to understand the frequency of 72 in 123825.

Going ahead to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 72

Moving on to step 2:
The number 72 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 72

Step 3:
If we divide 123 by 72, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 72 from 123 and we're left with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 72

Advancing to step 4:
When dividing 518 by 72, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 504 from 518 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 72

Moving on to step 5:
If we divide 142 by 72, we get 1 and a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtract 72 from 142 to get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 72

Advancing to step 6:
705 divided by 72 is 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 1719.0
The remainder is 57 after subtracting 648 from 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 72, we get 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 1719.7
Subtract 504 from 570 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.

Step 8:
660 divided by 72 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 1719.79
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.

Advancing to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 1719.791
Deduct 72 from 120 and we're left 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.
Write down 6 as next digit of the result. 
Result so far: 1719.7916
Deduct 432 from 480 and we're left 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 11:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 1719.79166
Deduct 432 from 480 and we're left 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.

Our division results in 1719.79166 with a remaining 4.8e-05.
