We're dividing 103287 by 72 
The aim is to understand the frequency of 72 in 103287.

Step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 72

On to step 2:
The number 72 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 72

Going ahead to step 3:
72 goes into 103 1 times with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 103 to get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 72

Let's proceed to step 4:
312 divided by 72 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 24 after subtracting 288 from 312.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 72

Moving on to step 5:
When dividing 248 by 72, we get 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtracting 216 from 248 leaves us with 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 72

Going ahead to step 6:
72 can be fit into 327 4 times, resulting in a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 1434.0
The remainder is 39 after subtracting 288 from 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
72 can be fit into 390 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 1434.5
Deduct 360 from 390 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 72, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1434.54
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 72 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1434.541
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.

Advancing to step 10:
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: 1434.5416
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.

Step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1434.54166
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 1434.54166 with a balance of 4.8e-05.
