81462775 ÷ 727 
The aim is to understand the frequency of 727 in 81462775.

Step 1:
The number 727 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 727

Going ahead to step 2:
81 divided by 727 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 727

Let's proceed to step 3:
727 can be fit into 814 1 times, resulting in a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 727 from 814 and we're left with 87.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 727

Step 4:
When dividing 876 by 727, we get 1 with a remainder of 149.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 727 from 876 leaves us with 149.
Grab the next digit (2) from the dividend, add it to 149, then carry on: 1492 / 727

Step 5:
727 goes into 1492 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1454 from 1492 to get 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 727

Moving on to step 6:
When dividing 387 by 727, we get 0 with a remainder of 387.
The number 0 becomes the next digit in our result. 
Result so far: 1120.0
If we subtract 0 from 387, we get 387.
Take the next digit (7) from the dividend and append it to 387, then repeat: 3877 / 727

Moving on to step 7:
727 goes into 3877 5 times with a remainder of 242.
Use 5 as the next digit of our solution. 
Result so far: 11205.0
Deduct 3635 from 3877 and we're left with 242.
Append the next digit (5) from the dividend to 242 and continue with: 2425 / 727

Moving on to step 8:
If we divide 2425 by 727, we get 3 and a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 112053.0
Deduct 2181 from 2425 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 9:
When dividing 2440 by 727, we get 3 with a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 112053.3
Subtracting 2181 from 2440 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 10:
727 can be fit into 2590 3 times, resulting in a remainder of 409.
The number 3 becomes the next digit in our result. 
Result so far: 112053.33
Subtract 2181 from 2590 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

After the division, we end up with 112053.33 and a remainder of 0.409.
