20826588 ÷ 72 
The aim is to understand the frequency of 72 in 20826588.

Step 1:
72 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 72

On to step 2:
When dividing 20 by 72, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 72

Step 3:
When dividing 208 by 72, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 144 away from 208, we end up with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 72

Step 4:
642 divided by 72 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 576 from 642 to get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 72

Advancing to step 5:
If we divide 666 by 72, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 289.0
The remainder is 18 after subtracting 648 from 666.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 72

Moving on to step 6:
When dividing 185 by 72, we get 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 2892.0
Subtracting 144 from 185 leaves us with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 72

Going ahead to step 7:
The number 72 fits into 418 5 times, leaving a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 28925.0
If we take 360 away from 418, we end up with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 72

Advancing to step 8:
The number 72 fits into 588 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 289258.0
Subtract 576 from 588 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 72 fits into 120 1 times, leaving a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 289258.1
Deduct 72 from 120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 289258.16
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
480 divided by 72 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 289258.166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 289258.166 with a balance of 0.0048.
