808002 ÷ 72 
The aim is to understand the frequency of 72 in 808002.

Let's proceed to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 72

Step 2:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 72 from 80 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 72

On to step 3:
72 goes into 88 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 72 away from 88, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 72

Let's proceed to step 4:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 144 from 160 leaves us with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 72

Moving on to step 5:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1122.0
The remainder is 16 after subtracting 144 from 160.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 72

Step 6:
If we divide 162 by 72, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 11222.0
The remainder is 18 after subtracting 144 from 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 72 fits into 180 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 11222.2
The remainder is 36 after subtracting 144 from 180.
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 8:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11222.25
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 72, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11222.25
Deduct 0 from 0 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.

Step 10:
72 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11222.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 11222.25 and a remainder of 0.0.
