68840609 ÷ 72 
The aim is to understand the frequency of 72 in 68840609.

Moving on to step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 72

Step 2:
When dividing 68 by 72, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 72

Moving on to step 3:
If we divide 688 by 72, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 40 after subtracting 648 from 688.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 72

Going ahead to step 4:
If we divide 404 by 72, we get 5 and a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 360 from 404 and we're left with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 72

Moving on to step 5:
72 can be fit into 440 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 956.0
The remainder is 8 after subtracting 432 from 440.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 72

On to step 6:
When dividing 86 by 72, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 9561.0
Subtracting 72 from 86 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 72

On to step 7:
140 divided by 72 is 1 with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 95611.0
Subtract 72 from 140 to get 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 72

On to step 8:
689 divided by 72 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 956119.0
If we subtract 648 from 689, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
72 goes into 410 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 956119.5
Deduct 360 from 410 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
The number 72 fits into 500 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 956119.56
If we take 432 away from 500, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
72 goes into 680 9 times with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 956119.569
If we subtract 648 from 680, 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.

Going ahead to step 12:
If we divide 320 by 72, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 956119.5694
Subtract 288 from 320 to 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.

Advancing to step 13:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 956119.56944
Subtracting 288 from 320 leaves us 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.

The quotient of the division is 956119.56944, and the remainder is 3.2e-05.
