We're dividing 36874563 by 72 
The aim is to understand the frequency of 72 in 36874563.

Step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 72

Going ahead to step 2:
72 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 72

Moving on to step 3:
368 divided by 72 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 360 from 368, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 72

Going ahead to step 4:
The number 72 fits into 87 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 72 from 87 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 72

Let's proceed to step 5:
The number 72 fits into 154 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 512.0
Subtract 144 from 154 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 72

Let's proceed to step 6:
72 goes into 105 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 5121.0
Subtract 72 from 105 to get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 72

Going ahead to step 7:
When dividing 336 by 72, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 51214.0
Subtract 288 from 336 to get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 72

Moving on to step 8:
72 goes into 483 6 times with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 512146.0
Subtracting 432 from 483 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
If we divide 510 by 72, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 512146.7
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
72 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 512146.7
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 72, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 512146.708
Deduct 576 from 600 and we're left 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.

Going ahead to step 12:
240 divided by 72 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 512146.7083
If we subtract 216 from 240, we 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.

Moving on to step 13:
72 goes into 240 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 512146.70833
If we take 216 away from 240, 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.

After the division, we end up with 512146.70833 and a remainder of 2.4e-05.
