177802 ÷ 72 
The aim is to understand the frequency of 72 in 177802.

Advancing to step 1:
1 divided by 72 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 72

Advancing to step 2:
17 divided by 72 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 72

On to step 3:
If we divide 177 by 72, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 33 after subtracting 144 from 177.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 72

Moving on to step 4:
72 goes into 338 4 times with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 288 from 338 and we're left with 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 72

Moving on to step 5:
The number 72 fits into 500 6 times, leaving a remainder of 68.
The next digit of our result is 6. 
Result so far: 246.0
If we subtract 432 from 500, we get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 72

On to step 6:
72 can be fit into 682 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 2469.0
Deduct 648 from 682 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.

Going ahead to step 7:
340 divided by 72 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 2469.4
Subtract 288 from 340 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
When dividing 520 by 72, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 2469.47
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.

Going ahead to step 9:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2469.472
If we take 144 away from 160, we end up 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.

Let's proceed to step 10:
160 divided by 72 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2469.4722
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 2469.4722 with a remainder of 0.00016.
