88117 ÷ 72 
The aim is to understand the frequency of 72 in 88117.

On to step 1:
8 divided by 72 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 72

Step 2:
The number 72 fits into 88 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 88, we get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 72

Moving on to step 3:
72 can be fit into 161 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 144 from 161 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 72

Going ahead to step 4:
If we divide 171 by 72, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 144 away from 171, we end up with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 72

Moving on to step 5:
72 goes into 277 3 times with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 1223.0
If we take 216 away from 277, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 6:
The number 72 fits into 610 8 times, leaving a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 1223.8
Deduct 576 from 610 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
72 goes into 340 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 1223.84
If we take 288 away from 340, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1223.847
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1223.8472
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1223.84722
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1223.84722 with a remainder of 1.6e-05.
