We divide 386591 by 71
The aim is to understand the frequency of 71 in 386591.

Advancing to step 1:
71 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 71

Step 2:
When dividing 38 by 71, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 71

Step 3:
When dividing 386 by 71, we get 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 355 from 386 and we're left with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 71

Step 4:
71 can be fit into 315 4 times, resulting in a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 284 from 315, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 71

Going ahead to step 5:
When dividing 319 by 71, we get 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
If we subtract 284 from 319, we get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 71

Going ahead to step 6:
71 goes into 351 4 times with a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 5444.0
Deduct 284 from 351 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
670 divided by 71 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 5444.9
The remainder is 31 after subtracting 639 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
71 goes into 310 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 5444.94
Deduct 284 from 310 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 71, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 5444.943
If we take 213 away from 260, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
470 divided by 71 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 5444.9436
Deduct 426 from 470 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
If we divide 440 by 71, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 5444.94366
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 5444.94366 and a remainder of 1.4e-05.
