We look at the division of 85655525 by 819 
The aim is to understand the frequency of 819 in 85655525.

Let's proceed to step 1:
8 divided by 819 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 819

Going ahead to step 2:
819 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 819

Going ahead to step 3:
If we divide 856 by 819, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 819 from 856 leaves us with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 819

On to step 4:
When dividing 375 by 819, we get 0 with a remainder of 375.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 375 leaves us with 375.
Fetch the next digit (5) from the dividend, attach it to 375 and continue: 3755 / 819

Step 5:
819 can be fit into 3755 4 times, resulting in a remainder of 479.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 3276 from 3755 and we're left with 479.
Append the next digit (5) from the dividend to 479 and continue with: 4795 / 819

Advancing to step 6:
819 can be fit into 4795 5 times, resulting in a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
If we subtract 4095 from 4795, we get 700.
Include the next digit (2) from the dividend after 700, then repeat: 7002 / 819

Advancing to step 7:
819 goes into 7002 8 times with a remainder of 450.
Put 8 as the next digit of the answer. 
Result so far: 10458.0
Subtracting 6552 from 7002 leaves us with 450.
Take the next digit (5) from the dividend and append it to 450, then repeat: 4505 / 819

Let's proceed to step 8:
819 can be fit into 4505 5 times, resulting in a remainder of 410.
The number 5 becomes the next digit in our result. 
Result so far: 104585.0
Deduct 4095 from 4505 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
4100 divided by 819 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 104585.5
Subtract 4095 from 4100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
819 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 104585.5
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.

Advancing to step 11:
When dividing 500 by 819, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 104585.5
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 104585.5 and a remainder of 0.05.
