841680 divided by 71 
The aim is to understand the frequency of 71 in 841680.

Step 1:
8 divided by 71 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 71

Advancing to step 2:
If we divide 84 by 71, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 71 from 84 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 71

Let's proceed to step 3:
The number 71 fits into 131 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 71 from 131 leaves us with 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 71

Going ahead to step 4:
71 can be fit into 606 8 times, resulting in a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
The remainder is 38 after subtracting 568 from 606.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 71

Moving on to step 5:
If we divide 388 by 71, we get 5 and a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 1185.0
The remainder is 33 after subtracting 355 from 388.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 71

Step 6:
71 goes into 330 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 11854.0
If we take 284 away from 330, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
If we divide 460 by 71, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 11854.6
If we subtract 426 from 460, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 71, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 11854.64
Subtract 284 from 340 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 71 is 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 11854.647
Subtracting 497 from 560 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
The number 71 fits into 630 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 11854.6478
If we subtract 568 from 630, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
71 goes into 620 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 11854.64788
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 11854.64788, and the remainder is 5.2e-05.
