We look at the division of 167409 by 71 
The aim is to understand the frequency of 71 in 167409.

Going ahead to step 1:
If we divide 1 by 71, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 71

Advancing to step 2:
71 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 71

Let's proceed to step 3:
71 goes into 167 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 142 from 167 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 71

Advancing to step 4:
When dividing 254 by 71, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 41 after subtracting 213 from 254.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 71

Let's proceed to step 5:
71 goes into 410 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
If we subtract 355 from 410, we get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 71

Moving on to step 6:
71 can be fit into 559 7 times, resulting in a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 2357.0
The remainder is 62 after subtracting 497 from 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
71 can be fit into 620 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 2357.8
The remainder is 52 after subtracting 568 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
If we divide 520 by 71, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 2357.87
The remainder is 23 after subtracting 497 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
71 goes into 230 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2357.873
The remainder is 17 after subtracting 213 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
71 can be fit into 170 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2357.8732
Subtract 142 from 170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
280 divided by 71 is 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 2357.87323
If we subtract 213 from 280, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 12:
When dividing 670 by 71, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2357.873239
The remainder is 31 after subtracting 639 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
If we divide 310 by 71, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2357.8732394
If we take 284 away from 310, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
71 goes into 260 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 2357.87323943
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 2357.87323943, with a leftover of 4.7e-08.
