225615 ÷ 72 
The aim is to understand the frequency of 72 in 225615.

Moving on to step 1:
72 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 72

Going ahead to step 2:
22 divided by 72 is 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 72

Moving on to step 3:
When dividing 225 by 72, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 216 from 225 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 72

Going ahead to step 4:
96 divided by 72 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 72 from 96 and we're left with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 72

Let's proceed to step 5:
72 can be fit into 241 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
If we subtract 216 from 241, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 72

Let's proceed to step 6:
72 goes into 255 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3133.0
Subtract 216 from 255 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
72 goes into 390 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3133.5
If we subtract 360 from 390, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
72 goes into 300 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3133.54
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 3133.541
Subtracting 72 from 120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 3133.5416
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
72 goes into 480 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 3133.54166
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 3133.54166, and the remainder is 4.8e-05.
