We look at the division of 180137 by 71 
The aim is to understand the frequency of 71 in 180137.

Moving on to step 1:
If we divide 1 by 71, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 71

Step 2:
If we divide 18 by 71, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 71

On to step 3:
If we divide 180 by 71, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 142 from 180 to get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 71

Advancing to step 4:
71 can be fit into 381 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 355 from 381 and we're left with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 71

Advancing to step 5:
If we divide 263 by 71, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 253.0
If we take 213 away from 263, we end up with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 71

Step 6:
71 can be fit into 507 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 2537.0
If we take 497 away from 507, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 71 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 2537.1
Subtracting 71 from 100 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
71 goes into 290 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 2537.14
If we subtract 284 from 290, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 71 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2537.14
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
71 can be fit into 600 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 2537.1408
Subtracting 568 from 600 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
When dividing 320 by 71, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 2537.14084
Deduct 284 from 320 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
The number 71 fits into 360 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2537.140845
If we subtract 355 from 360, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
71 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 2537.140845
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 71, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2537.14084507
If we take 497 away from 500, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 2537.14084507 with a balance of 3e-09.
