We look at the division of 66311092 by 395 
The aim is to understand the frequency of 395 in 66311092.

Moving on to step 1:
395 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 395

Step 2:
When dividing 66 by 395, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 395

Let's proceed to step 3:
395 can be fit into 663 1 times, resulting in a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 395 away from 663, we end up with 268.
Bring next digit (1) of the dividend behind the 268 and repeat the process: 2681 / 395

On to step 4:
395 can be fit into 2681 6 times, resulting in a remainder of 311.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 2370 from 2681 to get 311.
Grab the next digit (1) from the dividend, add it to 311, then carry on: 3111 / 395

Let's proceed to step 5:
395 goes into 3111 7 times with a remainder of 346.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we take 2765 away from 3111, we end up with 346.
Include the next digit (0) from the dividend after 346, then repeat: 3460 / 395

Let's proceed to step 6:
When dividing 3460 by 395, we get 8 with a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 1678.0
The remainder is 300 after subtracting 3160 from 3460.
Bring next digit (9) of the dividend behind the 300 and repeat the process: 3009 / 395

On to step 7:
The number 395 fits into 3009 7 times, leaving a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 16787.0
The remainder is 244 after subtracting 2765 from 3009.
Fetch the next digit (2) from the dividend, attach it to 244 and continue: 2442 / 395

On to step 8:
When dividing 2442 by 395, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 167876.0
The remainder is 72 after subtracting 2370 from 2442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
720 divided by 395 is 1 with a remainder of 325.
The next digit of our result is 1. 
Result so far: 167876.1
The remainder is 325 after subtracting 395 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 10:
When dividing 3250 by 395, we get 8 with a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 167876.18
If we take 3160 away from 3250, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
900 divided by 395 is 2 with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 167876.182
If we take 790 away from 900, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
395 can be fit into 1100 2 times, resulting in a remainder of 310.
Record the quotient 2 as the next digit in the result. 
Result so far: 167876.1822
Subtracting 790 from 1100 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 167876.1822, with a leftover of 0.0031.
