We divide 43566761 by 855
The aim is to understand the frequency of 855 in 43566761.

On to step 1:
855 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 855

Let's proceed to step 2:
855 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 855

Step 3:
855 goes into 435 0 times with a remainder of 435.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 435 after subtracting 0 from 435.
Take the next digit (6) from the dividend and append it to 435, then repeat: 4356 / 855

Let's proceed to step 4:
855 goes into 4356 5 times with a remainder of 81.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4275 from 4356 leaves us with 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 855

Let's proceed to step 5:
If we divide 816 by 855, we get 0 and a remainder of 816.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 816 and we're left with 816.
Append the next digit (7) from the dividend to 816 and continue with: 8167 / 855

Going ahead to step 6:
855 goes into 8167 9 times with a remainder of 472.
Put 9 as the next digit of the answer. 
Result so far: 509.0
If we subtract 7695 from 8167, we get 472.
Fetch the next digit (6) from the dividend, attach it to 472 and continue: 4726 / 855

Let's proceed to step 7:
4726 divided by 855 is 5 with a remainder of 451.
The next digit of our result is 5. 
Result so far: 5095.0
If we take 4275 away from 4726, we end up with 451.
Fetch the next digit (1) from the dividend, attach it to 451 and continue: 4511 / 855

Going ahead to step 8:
855 goes into 4511 5 times with a remainder of 236.
Write down 5 as next digit of the result. 
Result so far: 50955.0
Subtracting 4275 from 4511 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 9:
If we divide 2360 by 855, we get 2 and a remainder of 650.
The number 2 becomes the next digit in our result. 
Result so far: 50955.2
If we subtract 1710 from 2360, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
855 can be fit into 6500 7 times, resulting in a remainder of 515.
The number 7 becomes the next digit in our result. 
Result so far: 50955.27
The remainder is 515 after subtracting 5985 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 11:
855 can be fit into 5150 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 50955.276
If we take 5130 away from 5150, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
855 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 50955.276
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
855 goes into 2000 2 times with a remainder of 290.
The next digit of our result is 2. 
Result so far: 50955.27602
Subtract 1710 from 2000 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
855 can be fit into 2900 3 times, resulting in a remainder of 335.
The next digit of our result is 3. 
Result so far: 50955.276023
If we subtract 2565 from 2900, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 15:
855 goes into 3350 3 times with a remainder of 785.
Use 3 as the next digit of our solution. 
Result so far: 50955.2760233
If we take 2565 away from 3350, we end up with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

The final outcome is 50955.2760233, with a leftover of 7.85e-06.
