We look at the division of 812411 by 72 
The aim is to understand the frequency of 72 in 812411.

Let's proceed to step 1:
8 divided by 72 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 72

Advancing to step 2:
72 goes into 81 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 72 from 81 and we're left with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 72

Let's proceed to step 3:
When dividing 92 by 72, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 72 away from 92, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 72

On to step 4:
72 can be fit into 204 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 112.0
If we take 144 away from 204, we end up with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 72

Going ahead to step 5:
72 can be fit into 601 8 times, resulting in a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 1128.0
Subtract 576 from 601 to get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 72

Moving on to step 6:
251 divided by 72 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 11283.0
The remainder is 35 after subtracting 216 from 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
72 goes into 350 4 times with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 11283.4
Deduct 288 from 350 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
When dividing 620 by 72, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 11283.48
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 11283.486
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11283.4861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
When dividing 80 by 72, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 11283.48611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 11283.48611 with a remaining 8e-06.
