862015 divided by 72 
The aim is to understand the frequency of 72 in 862015.

On to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 72

On to step 2:
When dividing 86 by 72, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 72 from 86 leaves us with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 72

On to step 3:
72 can be fit into 142 1 times, resulting in a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 72 from 142 leaves us with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 72

Going ahead to step 4:
When dividing 700 by 72, we get 9 with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 648 from 700 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 72

Advancing to step 5:
72 can be fit into 521 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 1197.0
If we take 504 away from 521, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 72

Moving on to step 6:
When dividing 175 by 72, we get 2 with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 11972.0
The remainder is 31 after subtracting 144 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
If we divide 310 by 72, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 11972.4
Subtracting 288 from 310 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
72 goes into 220 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 11972.43
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
72 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11972.43
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 72 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 11972.4305
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 72, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 11972.43055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 11972.43055 with a remaining 4e-05.
