We look at the division of 800924 by 71 
The aim is to understand the frequency of 71 in 800924.

Going ahead to step 1:
71 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 71

Let's proceed to step 2:
If we divide 80 by 71, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 71 from 80.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 71

Step 3:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 19 after subtracting 71 from 90.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 71

On to step 4:
If we divide 199 by 71, we get 2 and a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we take 142 away from 199, we end up with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 71

Moving on to step 5:
71 can be fit into 572 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
The remainder is 4 after subtracting 568 from 572.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 71

Moving on to step 6:
The number 71 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 11280.0
If we subtract 0 from 44, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
71 can be fit into 440 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 11280.6
Subtracting 426 from 440 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 71 fits into 140 1 times, leaving a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 11280.61
Subtracting 71 from 140 leaves us 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.

Moving on to step 9:
690 divided by 71 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 11280.619
Subtract 639 from 690 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
71 can be fit into 510 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 11280.6197
If we subtract 497 from 510, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
When dividing 130 by 71, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 11280.61971
Subtracting 71 from 130 leaves us 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.

Moving on to step 12:
When dividing 590 by 71, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 11280.619718
If we take 568 away from 590, we end up 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.

Going ahead to step 13:
When dividing 220 by 71, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 11280.6197183
If we take 213 away from 220, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
71 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 11280.6197183
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 11280.6197183 with a remainder of 7e-08.
