82215810 divided by 72 
The aim is to understand the frequency of 72 in 82215810.

Step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 72

Going ahead to step 2:
If we divide 82 by 72, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 72 away from 82, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 72

Going ahead to step 3:
The number 72 fits into 102 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 30 after subtracting 72 from 102.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 72

Advancing to step 4:
When dividing 301 by 72, we get 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 114.0
The remainder is 13 after subtracting 288 from 301.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 72

Going ahead to step 5:
When dividing 135 by 72, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 1141.0
If we take 72 away from 135, we end up with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 72

Going ahead to step 6:
72 can be fit into 638 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 11418.0
Deduct 576 from 638 and we're left with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 72

On to step 7:
If we divide 621 by 72, we get 8 and a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 114188.0
Deduct 576 from 621 and we're left with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 72

Moving on to step 8:
450 divided by 72 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1141886.0
Subtract 432 from 450 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
72 goes into 180 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1141886.2
Subtracting 144 from 180 leaves us 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.

Going ahead to step 10:
72 goes into 360 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1141886.25
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.

On to step 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1141886.25
If we take 0 away from 0, 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.

Moving on to step 12:
When dividing 0 by 72, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1141886.25
If we take 0 away from 0, 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.

The final outcome is 1141886.25, with a leftover of 0.0.
