381386 ÷ 71 
The aim is to understand the frequency of 71 in 381386.

Going ahead to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 71

Let's proceed to step 2:
When dividing 38 by 71, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 71

Let's proceed to step 3:
If we divide 381 by 71, we get 5 and a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 355 from 381 and we're left with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 71

Let's proceed to step 4:
When dividing 263 by 71, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 213 from 263, we get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 71

Step 5:
71 goes into 508 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 537.0
If we subtract 497 from 508, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 71

Moving on to step 6:
116 divided by 71 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 5371.0
If we subtract 71 from 116, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
When dividing 450 by 71, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 5371.6
If we take 426 away from 450, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
The number 71 fits into 240 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 5371.63
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 71 fits into 270 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 5371.633
Deduct 213 from 270 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 5371.633 with a remaining 0.0057.
