Let's divide 279513 by 72
The aim is to understand the frequency of 72 in 279513.

Let's proceed to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 72

Going ahead to step 2:
When dividing 27 by 72, we get 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 72

Advancing to step 3:
72 goes into 279 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 216 from 279 to get 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 72

Moving on to step 4:
72 goes into 635 8 times with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 576 from 635 leaves us with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 72

Going ahead to step 5:
The number 72 fits into 591 8 times, leaving a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
The remainder is 15 after subtracting 576 from 591.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 72

Step 6:
72 goes into 153 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 3882.0
Subtract 144 from 153 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 72, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 3882.1
Subtract 72 from 90 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 72, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 3882.12
Subtracting 144 from 180 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 72, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3882.125
Deduct 360 from 360 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 72, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3882.125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3882.125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3882.125, with a leftover of 0.0.
