We look at the division of 85774789 by 395 
The aim is to understand the frequency of 395 in 85774789.

Step 1:
395 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 395

Moving on to step 2:
The number 395 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 395

Step 3:
When dividing 857 by 395, we get 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 67 after subtracting 790 from 857.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 395

Going ahead to step 4:
677 divided by 395 is 1 with a remainder of 282.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 395 away from 677, we end up with 282.
Fetch the next digit (4) from the dividend, attach it to 282 and continue: 2824 / 395

Advancing to step 5:
395 goes into 2824 7 times with a remainder of 59.
The next digit of our result is 7. 
Result so far: 217.0
If we subtract 2765 from 2824, we get 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 395

Going ahead to step 6:
When dividing 597 by 395, we get 1 with a remainder of 202.
The next digit of our result is 1. 
Result so far: 2171.0
If we subtract 395 from 597, we get 202.
Fetch the next digit (8) from the dividend, attach it to 202 and continue: 2028 / 395

On to step 7:
395 goes into 2028 5 times with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 21715.0
If we take 1975 away from 2028, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 395

Going ahead to step 8:
539 divided by 395 is 1 with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 217151.0
If we subtract 395 from 539, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
When dividing 1440 by 395, we get 3 with a remainder of 255.
Put 3 as the next digit of the answer. 
Result so far: 217151.3
Deduct 1185 from 1440 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 10:
395 goes into 2550 6 times with a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 217151.36
Subtract 2370 from 2550 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
395 can be fit into 1800 4 times, resulting in a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 217151.364
Subtract 1580 from 1800 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
The number 395 fits into 2200 5 times, leaving a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 217151.3645
Subtracting 1975 from 2200 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 13:
If we divide 2250 by 395, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 217151.36455
If we subtract 1975 from 2250, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

After the division, we end up with 217151.36455 and a remainder of 0.000275.
