We look at the division of 798510 by 71 
The aim is to understand the frequency of 71 in 798510.

Let's proceed to step 1:
If we divide 7 by 71, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 71

Going ahead to step 2:
When dividing 79 by 71, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 71 from 79, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 71

On to step 3:
The number 71 fits into 88 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 71 away from 88, we end up with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 71

Step 4:
71 goes into 175 2 times with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 33 after subtracting 142 from 175.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 71

On to step 5:
If we divide 331 by 71, we get 4 and a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 1124.0
Deduct 284 from 331 and we're left with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 71

On to step 6:
When dividing 470 by 71, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 11246.0
Subtract 426 from 470 to 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.

On to step 7:
71 goes into 440 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 11246.6
Deduct 426 from 440 and we're left 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.

Going ahead to step 8:
When dividing 140 by 71, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 11246.61
Subtract 71 from 140 to get 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 9:
The number 71 fits into 690 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 11246.619
If we subtract 639 from 690, we 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.

Step 10:
510 divided by 71 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 11246.6197
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:
130 divided by 71 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 11246.61971
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.

Step 12:
When dividing 590 by 71, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 11246.619718
If we subtract 568 from 590, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
71 goes into 220 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 11246.6197183
If we subtract 213 from 220, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
71 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 11246.6197183
If we subtract 0 from 70, we get 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 quotient of the division is 11246.6197183, and the remainder is 7e-08.
