We're dividing 81865794 by 784 
The aim is to understand the frequency of 784 in 81865794.

Step 1:
If we divide 8 by 784, we get 0 and a remainder of 8.
Write down 0 as next digit of 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 / 784

Advancing to step 2:
784 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 784

Going ahead to step 3:
784 goes into 818 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 784 from 818 to get 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 784

Let's proceed to step 4:
784 can be fit into 346 0 times, resulting in a remainder of 346.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 346 after subtracting 0 from 346.
Take the next digit (5) from the dividend and append it to 346, then repeat: 3465 / 784

Moving on to step 5:
3465 divided by 784 is 4 with a remainder of 329.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 3136 from 3465 and we're left with 329.
Append the next digit (7) from the dividend to 329 and continue with: 3297 / 784

Moving on to step 6:
3297 divided by 784 is 4 with a remainder of 161.
Put 4 as the next digit of the answer. 
Result so far: 1044.0
The remainder is 161 after subtracting 3136 from 3297.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 784

Going ahead to step 7:
The number 784 fits into 1619 2 times, leaving a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 10442.0
Subtract 1568 from 1619 to get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 784

Let's proceed to step 8:
514 divided by 784 is 0 with a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 104420.0
Subtract 0 from 514 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 9:
The number 784 fits into 5140 6 times, leaving a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 104420.6
Subtracting 4704 from 5140 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 10:
If we divide 4360 by 784, we get 5 and a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 104420.65
Deduct 3920 from 4360 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
784 goes into 4400 5 times with a remainder of 480.
Record the quotient 5 as the next digit in the result. 
Result so far: 104420.655
If we take 3920 away from 4400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 104420.655 with a balance of 0.048.
