Let's divide 7126 by 395
The aim is to understand the frequency of 395 in 7126.

Advancing to step 1:
395 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 395

Advancing to step 2:
395 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 395

Step 3:
If we divide 712 by 395, we get 1 and a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 395 away from 712, we end up with 317.
Take the next digit (6) from the dividend and append it to 317, then repeat: 3176 / 395

Going ahead to step 4:
If we divide 3176 by 395, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3160 from 3176 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 5:
When dividing 160 by 395, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 18.0
Subtracting 0 from 160 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 6:
The number 395 fits into 1600 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 18.04
Deduct 1580 from 1600 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 395, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 18.04
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 8:
The number 395 fits into 2000 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 18.0405
If we take 1975 away from 2000, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
395 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 18.0405
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
The number 395 fits into 2500 6 times, leaving a remainder of 130.
The next digit of our result is 6. 
Result so far: 18.040506
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.

Moving on to step 11:
The number 395 fits into 1300 3 times, leaving a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 18.0405063
If we subtract 1185 from 1300, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
395 can be fit into 1150 2 times, resulting in a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 18.04050632
Deduct 790 from 1150 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 18.04050632, with a leftover of 3.6e-07.
