15126036 ÷ 72 
The aim is to understand the frequency of 72 in 15126036.

Going ahead to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 72

Going ahead to step 2:
The number 72 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 72

Going ahead to step 3:
When dividing 151 by 72, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
If we take 144 away from 151, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 72

Advancing to step 4:
The number 72 fits into 72 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 72 away from 72, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 72

Advancing to step 5:
6 divided by 72 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 210.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 72

Let's proceed to step 6:
72 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 2100.0
Subtracting 0 from 60 leaves us with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 72

Moving on to step 7:
If we divide 603 by 72, we get 8 and a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 21008.0
If we take 576 away from 603, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 72

On to step 8:
276 divided by 72 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 210083.0
The remainder is 60 after subtracting 216 from 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
72 goes into 600 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 210083.8
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 210083.83
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 72 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 210083.833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 210083.833, and the remainder is 0.0024.
