We look at the division of 26163735 by 71 
The aim is to understand the frequency of 71 in 26163735.

Going ahead to step 1:
71 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 71

On to step 2:
When dividing 26 by 71, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 71

Moving on to step 3:
When dividing 261 by 71, we get 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 213 from 261 to get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 71

Going ahead to step 4:
486 divided by 71 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 426 from 486, we get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 71

Let's proceed to step 5:
603 divided by 71 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 368.0
Deduct 568 from 603 and we're left with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 71

On to step 6:
If we divide 357 by 71, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 3685.0
The remainder is 2 after subtracting 355 from 357.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 71

Step 7:
The number 71 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 36850.0
If we subtract 0 from 23, we get 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 71

Advancing to step 8:
When dividing 235 by 71, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 368503.0
If we subtract 213 from 235, 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 9:
When dividing 220 by 71, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 368503.3
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.

Let's proceed to step 10:
When dividing 70 by 71, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 368503.3
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.

Step 11:
71 goes into 700 9 times with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 368503.309
Subtract 639 from 700 to get 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 12:
71 can be fit into 610 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 368503.3098
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.

Moving on to step 13:
420 divided by 71 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 368503.30985
Subtract 355 from 420 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
71 goes into 650 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 368503.309859
The remainder is 11 after subtracting 639 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
71 can be fit into 110 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 368503.3098591
The remainder is 39 after subtracting 71 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 16:
390 divided by 71 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 368503.30985915
Deduct 355 from 390 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 368503.30985915, and the remainder is 3.5e-08.
