68868221 ÷ 855 
The aim is to understand the frequency of 855 in 68868221.

Moving on to step 1:
6 divided by 855 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 855

Going ahead to step 2:
855 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 855

Step 3:
855 can be fit into 688 0 times, resulting in a remainder of 688.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 688, we get 688.
Append the next digit (6) from the dividend to 688 and continue with: 6886 / 855

Moving on to step 4:
855 goes into 6886 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6840 away from 6886, we end up with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 855

Step 5:
855 can be fit into 468 0 times, resulting in a remainder of 468.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
The remainder is 468 after subtracting 0 from 468.
Take the next digit (2) from the dividend and append it to 468, then repeat: 4682 / 855

Advancing to step 6:
4682 divided by 855 is 5 with a remainder of 407.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
If we take 4275 away from 4682, we end up with 407.
Append the next digit (2) from the dividend to 407 and continue with: 4072 / 855

Step 7:
4072 divided by 855 is 4 with a remainder of 652.
Put 4 as the next digit of the answer. 
Result so far: 8054.0
The remainder is 652 after subtracting 3420 from 4072.
Append the next digit (1) from the dividend to 652 and continue with: 6521 / 855

Let's proceed to step 8:
If we divide 6521 by 855, we get 7 and a remainder of 536.
Use 7 as the next digit of our solution. 
Result so far: 80547.0
Deduct 5985 from 6521 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 9:
855 goes into 5360 6 times with a remainder of 230.
Put 6 as the next digit of the answer. 
Result so far: 80547.6
If we subtract 5130 from 5360, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
If we divide 2300 by 855, we get 2 and a remainder of 590.
The next digit of our result is 2. 
Result so far: 80547.62
Subtract 1710 from 2300 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 11:
When dividing 5900 by 855, we get 6 with a remainder of 770.
Use 6 as the next digit of our solution. 
Result so far: 80547.626
If we take 5130 away from 5900, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 12:
The number 855 fits into 7700 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 80547.6269
The remainder is 5 after subtracting 7695 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
855 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 80547.6269
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 855, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 80547.6269
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 80547.6269 with a remaining 5e-05.
