275378 divided by 72 
The aim is to understand the frequency of 72 in 275378.

Advancing to step 1:
The number 72 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 72

Going ahead to step 2:
When dividing 27 by 72, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 72

Going ahead to step 3:
The number 72 fits into 275 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 216 from 275 leaves us with 59.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 72

Step 4:
593 divided by 72 is 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 576 from 593, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 72

On to step 5:
When dividing 177 by 72, we get 2 with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 382.0
Deduct 144 from 177 and we're left with 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 72

On to step 6:
The number 72 fits into 338 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 3824.0
If we take 288 away from 338, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
When dividing 500 by 72, we get 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 3824.6
If we take 432 away from 500, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
The number 72 fits into 680 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 3824.69
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 3824.694
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
72 goes into 320 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3824.6944
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 3824.6944, with a leftover of 0.00032.
