678730 ÷ 71 
The aim is to understand the frequency of 71 in 678730.

Step 1:
If we divide 6 by 71, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 71

Let's proceed to step 2:
The number 71 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 71

Advancing to step 3:
678 divided by 71 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 639 from 678 and we're left with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 71

Moving on to step 4:
The number 71 fits into 397 5 times, leaving a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 42 after subtracting 355 from 397.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 71

Moving on to step 5:
423 divided by 71 is 5 with a remainder of 68.
Write down 5 as next digit of the result. 
Result so far: 955.0
If we take 355 away from 423, we end up with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 71

Going ahead to step 6:
71 goes into 680 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9559.0
The remainder is 41 after subtracting 639 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
71 can be fit into 410 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 9559.5
If we take 355 away from 410, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
550 divided by 71 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 9559.57
Subtract 497 from 550 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
71 goes into 530 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 9559.577
If we take 497 away from 530, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 9559.577 with a remaining 0.0033.
