We're dividing 82089132 by 72 
The aim is to understand the frequency of 72 in 82089132.

On to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
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

On to step 2:
82 divided by 72 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 82 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 72

Moving on to step 3:
If we divide 100 by 72, we get 1 and a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 72 from 100 and we're left with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 72

On to step 4:
72 can be fit into 288 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 114.0
Deduct 288 from 288 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 72

Step 5:
72 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 72

Moving on to step 6:
The number 72 fits into 91 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 11401.0
Subtract 72 from 91 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 72

Moving on to step 7:
72 goes into 193 2 times with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 114012.0
The remainder is 49 after subtracting 144 from 193.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 72

On to step 8:
When dividing 492 by 72, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1140126.0
The remainder is 60 after subtracting 432 from 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 1140126.8
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 72 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1140126.83
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 1140126.833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 1140126.833, with a leftover of 0.0024.
