Let's divide 68166392 by 72
The aim is to understand the frequency of 72 in 68166392.

Advancing to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 72

Advancing to step 2:
72 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 72

Let's proceed to step 3:
72 goes into 681 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 648 from 681 leaves us with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 72

Going ahead to step 4:
72 goes into 336 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 94.0
If we subtract 288 from 336, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 72

Moving on to step 5:
If we divide 486 by 72, we get 6 and a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 946.0
Subtract 432 from 486 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 72

On to step 6:
72 goes into 543 7 times with a remainder of 39.
The next digit of our result is 7. 
Result so far: 9467.0
If we subtract 504 from 543, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 72

Step 7:
399 divided by 72 is 5 with a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 94675.0
The remainder is 39 after subtracting 360 from 399.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 72

Moving on to step 8:
72 goes into 392 5 times with a remainder of 32.
The next digit of our result is 5. 
Result so far: 946755.0
If we take 360 away from 392, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 946755.4
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
72 goes into 320 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 946755.44
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 946755.44 and a remainder of 0.032.
