17237586 ÷ 143 
The aim is to understand the frequency of 143 in 17237586.

Going ahead to step 1:
If we divide 1 by 143, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 143

Let's proceed to step 2:
143 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 143

Step 3:
The number 143 fits into 172 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 143 from 172, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 143

Let's proceed to step 4:
143 can be fit into 293 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 7 after subtracting 286 from 293.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 143

Advancing to step 5:
The number 143 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 143

Going ahead to step 6:
If we divide 775 by 143, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
The remainder is 60 after subtracting 715 from 775.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 143

On to step 7:
If we divide 608 by 143, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 12054.0
If we subtract 572 from 608, we get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 143

On to step 8:
143 can be fit into 366 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 120542.0
If we subtract 286 from 366, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
143 goes into 800 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 120542.5
The remainder is 85 after subtracting 715 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
If we divide 850 by 143, we get 5 and a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 120542.55
Subtract 715 from 850 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

In conclusion, the division gives 120542.55 with a balance of 0.135.
