We're dividing 39022219 by 855 
The aim is to understand the frequency of 855 in 39022219.

Let's proceed to step 1:
When dividing 3 by 855, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 855

Let's proceed to step 2:
855 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 855

On to step 3:
855 goes into 390 0 times with a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 390, we get 390.
Grab the next digit (2) from the dividend, add it to 390, then carry on: 3902 / 855

Moving on to step 4:
3902 divided by 855 is 4 with a remainder of 482.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3420 from 3902, we get 482.
Grab the next digit (2) from the dividend, add it to 482, then carry on: 4822 / 855

Let's proceed to step 5:
When dividing 4822 by 855, we get 5 with a remainder of 547.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 4275 from 4822 leaves us with 547.
Append the next digit (2) from the dividend to 547 and continue with: 5472 / 855

Advancing to step 6:
5472 divided by 855 is 6 with a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Deduct 5130 from 5472 and we're left with 342.
Fetch the next digit (1) from the dividend, attach it to 342 and continue: 3421 / 855

Step 7:
The number 855 fits into 3421 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4564.0
Deduct 3420 from 3421 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 855

Going ahead to step 8:
When dividing 19 by 855, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 45640.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
190 divided by 855 is 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 45640.0
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
855 goes into 1900 2 times with a remainder of 190.
The next digit of our result is 2. 
Result so far: 45640.02
Subtracting 1710 from 1900 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
When dividing 1900 by 855, we get 2 with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 45640.022
Subtract 1710 from 1900 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 45640.022 and a remainder of 0.019.
