915778 divided by 72 
The aim is to understand the frequency of 72 in 915778.

Advancing to step 1:
72 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 72

On to step 2:
When dividing 91 by 72, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 91 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 72

On to step 3:
If we divide 195 by 72, we get 2 and a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 144 from 195 and we're left with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 72

Step 4:
If we divide 517 by 72, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 504 from 517 and we're left with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 72

Moving on to step 5:
72 can be fit into 137 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1271.0
If we subtract 72 from 137, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 72

Going ahead to step 6:
The number 72 fits into 658 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 12719.0
Deduct 648 from 658 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 72 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 12719.1
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
If we divide 280 by 72, we get 3 and a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 12719.13
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 12719.138
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 12719.1388
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 12719.1388 with a remainder of 0.00064.
