396069 divided by 71 
The aim is to understand the frequency of 71 in 396069.

Let's proceed to step 1:
71 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 71

Let's proceed to step 2:
71 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 71

Moving on to step 3:
If we divide 396 by 71, we get 5 and a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 355 away from 396, we end up with 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 71

Going ahead to step 4:
71 goes into 410 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 355 from 410, we get 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 71

Moving on to step 5:
71 goes into 556 7 times with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 557.0
If we take 497 away from 556, we end up with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 71

Let's proceed to step 6:
599 divided by 71 is 8 with a remainder of 31.
The next digit of our result is 8. 
Result so far: 5578.0
Deduct 568 from 599 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
71 can be fit into 310 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 5578.4
If we subtract 284 from 310, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
When dividing 260 by 71, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5578.43
Deduct 213 from 260 and we're left 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.

On to step 9:
The number 71 fits into 470 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 5578.436
Subtracting 426 from 470 leaves us 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.

Moving on to step 10:
The number 71 fits into 440 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 5578.4366
If we subtract 426 from 440, we 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.

The final result is 5578.4366 with a remainder of 0.00014.
