We look at the division of 722590 by 71 
The aim is to understand the frequency of 71 in 722590.

Moving on to step 1:
When dividing 7 by 71, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 71

Let's proceed to step 2:
If we divide 72 by 71, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 71 away from 72, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 71

Moving on to step 3:
71 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 71

Advancing to step 4:
If we divide 125 by 71, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 71 away from 125, we end up with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 71

Moving on to step 5:
If we divide 549 by 71, we get 7 and a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
Subtracting 497 from 549 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 71

Let's proceed to step 6:
520 divided by 71 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 10177.0
Deduct 497 from 520 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
71 goes into 230 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 10177.3
Subtract 213 from 230 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
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: 10177.32
If we subtract 142 from 170, we 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.

On to step 9:
If we divide 280 by 71, we get 3 and a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 10177.323
The remainder is 67 after subtracting 213 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
71 can be fit into 670 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 10177.3239
Subtract 639 from 670 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
71 can be fit into 310 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10177.32394
If we subtract 284 from 310, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
71 goes into 260 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 10177.323943
Deduct 213 from 260 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
71 goes into 470 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 10177.3239436
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.

Let's proceed to step 14:
71 can be fit into 440 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 10177.32394366
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.

In conclusion, the division gives 10177.32394366 with a balance of 1.4e-08.
