We look at the division of 437874 by 72 
The aim is to understand the frequency of 72 in 437874.

Going ahead to step 1:
72 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 72

Going ahead to step 2:
When dividing 43 by 72, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 72

Going ahead to step 3:
72 goes into 437 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 432 from 437 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 72

Moving on to step 4:
72 can be fit into 58 0 times, resulting in a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 58 to get 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 72

Step 5:
72 goes into 587 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
If we take 576 away from 587, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 72

Advancing to step 6:
72 can be fit into 114 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 6081.0
Subtracting 72 from 114 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 72 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 6081.5
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
600 divided by 72 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 6081.58
Subtracting 576 from 600 leaves us 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 9:
240 divided by 72 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 6081.583
Deduct 216 from 240 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.

Let's proceed to step 10:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 6081.5833
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.

The quotient of the division is 6081.5833, and the remainder is 0.00024.
