We look at the division of 841807 by 72 
The aim is to understand the frequency of 72 in 841807.

Let's proceed to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 72

On to step 2:
If we divide 84 by 72, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 72 away from 84, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 72

Let's proceed to step 3:
When dividing 121 by 72, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 72 from 121, we get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 72

Moving on to step 4:
72 can be fit into 498 6 times, resulting in a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
The remainder is 66 after subtracting 432 from 498.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 72

Step 5:
72 goes into 660 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 1169.0
The remainder is 12 after subtracting 648 from 660.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 72

On to step 6:
If we divide 127 by 72, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 11691.0
The remainder is 55 after subtracting 72 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
When dividing 550 by 72, we get 7 with a remainder of 46.
The next digit of our result is 7. 
Result so far: 11691.7
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
The number 72 fits into 460 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 11691.76
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
72 can be fit into 280 3 times, resulting in a remainder of 64.
The next digit of our result is 3. 
Result so far: 11691.763
If we take 216 away from 280, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
When dividing 640 by 72, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 11691.7638
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
If we divide 640 by 72, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 11691.76388
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 11691.76388 with a balance of 6.4e-05.
