Let's divide 42268051 by 395
The aim is to understand the frequency of 395 in 42268051.

On to step 1:
395 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 395

Step 2:
42 divided by 395 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 395

Step 3:
If we divide 422 by 395, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 27 after subtracting 395 from 422.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 395

Going ahead to step 4:
276 divided by 395 is 0 with a remainder of 276.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 276, we get 276.
Bring next digit (8) of the dividend behind the 276 and repeat the process: 2768 / 395

Advancing to step 5:
The number 395 fits into 2768 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 2765 from 2768 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 395

Advancing to step 6:
30 divided by 395 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1070.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 395

Step 7:
395 can be fit into 305 0 times, resulting in a remainder of 305.
The next digit of our result is 0. 
Result so far: 10700.0
Subtract 0 from 305 to get 305.
Include the next digit (1) from the dividend after 305, then repeat: 3051 / 395

Going ahead to step 8:
395 can be fit into 3051 7 times, resulting in a remainder of 286.
Put 7 as the next digit of the answer. 
Result so far: 107007.0
Subtract 2765 from 3051 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 9:
The number 395 fits into 2860 7 times, leaving a remainder of 95.
The next digit of our result is 7. 
Result so far: 107007.7
Subtract 2765 from 2860 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
The number 395 fits into 950 2 times, leaving a remainder of 160.
The next digit of our result is 2. 
Result so far: 107007.72
Subtracting 790 from 950 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
If we divide 1600 by 395, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 107007.724
If we subtract 1580 from 1600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 395 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 107007.724
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
395 goes into 2000 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 107007.72405
Subtract 1975 from 2000 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
When dividing 250 by 395, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 107007.72405
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 15:
395 can be fit into 2500 6 times, resulting in a remainder of 130.
Record the quotient 6 as the next digit in the result. 
Result so far: 107007.7240506
The remainder is 130 after subtracting 2370 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
If we divide 1300 by 395, we get 3 and a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 107007.72405063
If we take 1185 away from 1300, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final result is 107007.72405063 with a remainder of 1.15e-07.
