We're dividing 81773439 by 856 
The aim is to understand the frequency of 856 in 81773439.

Moving on to step 1:
856 goes into 8 0 times with 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 856

Going ahead to step 2:
The number 856 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 856

Let's proceed to step 3:
If we divide 817 by 856, we get 0 and a remainder of 817.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 817 to get 817.
Fetch the next digit (7) from the dividend, attach it to 817 and continue: 8177 / 856

Step 4:
If we divide 8177 by 856, we get 9 and a remainder of 473.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7704 from 8177 and we're left with 473.
Include the next digit (3) from the dividend after 473, then repeat: 4733 / 856

On to step 5:
If we divide 4733 by 856, we get 5 and a remainder of 453.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtracting 4280 from 4733 leaves us with 453.
Fetch the next digit (4) from the dividend, attach it to 453 and continue: 4534 / 856

On to step 6:
When dividing 4534 by 856, we get 5 with a remainder of 254.
Write down 5 as next digit of the result. 
Result so far: 955.0
Deduct 4280 from 4534 and we're left with 254.
Take the next digit (3) from the dividend and append it to 254, then repeat: 2543 / 856

Moving on to step 7:
2543 divided by 856 is 2 with a remainder of 831.
The next digit of our result is 2. 
Result so far: 9552.0
If we take 1712 away from 2543, we end up with 831.
Bring next digit (9) of the dividend behind the 831 and repeat the process: 8319 / 856

Step 8:
When dividing 8319 by 856, we get 9 with a remainder of 615.
The next digit of our result is 9. 
Result so far: 95529.0
Subtract 7704 from 8319 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Step 9:
856 goes into 6150 7 times with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 95529.7
Subtracting 5992 from 6150 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 10:
If we divide 1580 by 856, we get 1 and a remainder of 724.
Put 1 as the next digit of the answer. 
Result so far: 95529.71
The remainder is 724 after subtracting 856 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Going ahead to step 11:
856 can be fit into 7240 8 times, resulting in a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 95529.718
Subtract 6848 from 7240 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
3920 divided by 856 is 4 with a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 95529.7184
Subtract 3424 from 3920 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
The number 856 fits into 4960 5 times, leaving a remainder of 680.
The next digit of our result is 5. 
Result so far: 95529.71845
Deduct 4280 from 4960 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 14:
856 can be fit into 6800 7 times, resulting in a remainder of 808.
The number 7 becomes the next digit in our result. 
Result so far: 95529.718457
If we subtract 5992 from 6800, we get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 15:
8080 divided by 856 is 9 with a remainder of 376.
The next digit of our result is 9. 
Result so far: 95529.7184579
Subtract 7704 from 8080 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 16:
856 goes into 3760 4 times with a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 95529.71845794
Subtracting 3424 from 3760 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 95529.71845794 and a remainder of 3.36e-07.
