768999 ÷ 71 
The aim is to understand the frequency of 71 in 768999.

Going ahead to step 1:
If we divide 7 by 71, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 71

Advancing to step 2:
71 goes into 76 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 71 away from 76, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 71

Let's proceed to step 3:
When dividing 58 by 71, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 71

Let's proceed to step 4:
71 goes into 589 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 568 from 589, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 71

Let's proceed to step 5:
The number 71 fits into 219 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 1083.0
If we subtract 213 from 219, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 71

Advancing to step 6:
71 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 10830.0
Deduct 0 from 69 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
71 goes into 690 9 times with a remainder of 51.
The next digit of our result is 9. 
Result so far: 10830.9
Subtracting 639 from 690 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
When dividing 510 by 71, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 10830.97
If we take 497 away from 510, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
130 divided by 71 is 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 10830.971
Deduct 71 from 130 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
590 divided by 71 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 10830.9718
Subtracting 568 from 590 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
When dividing 220 by 71, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10830.97183
The remainder is 7 after subtracting 213 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
71 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10830.97183
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
If we divide 700 by 71, we get 9 and a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 10830.9718309
If we take 639 away from 700, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 14:
71 can be fit into 610 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 10830.97183098
Subtract 568 from 610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 10830.97183098, with a leftover of 4.2e-08.
