801567 ÷ 72 
The aim is to understand the frequency of 72 in 801567.

Step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the 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

Advancing to step 2:
80 divided by 72 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 72 from 80 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 72

Going ahead to step 3:
When dividing 81 by 72, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 72 from 81 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 72

Let's proceed to step 4:
95 divided by 72 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 111.0
Deduct 72 from 95 and we're left with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 72

Advancing to step 5:
The number 72 fits into 236 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 1113.0
If we subtract 216 from 236, we get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 72

On to step 6:
72 goes into 207 2 times with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 11132.0
If we subtract 144 from 207, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
The number 72 fits into 630 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 11132.8
Subtracting 576 from 630 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
72 goes into 540 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 11132.87
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
When dividing 360 by 72, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 11132.875
If we take 360 away from 360, we end up 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.

Advancing to step 10:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11132.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 72 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11132.875
If we subtract 0 from 0, we 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.

The final outcome is 11132.875, with a leftover of 0.0.
