We're dividing 2645997 by 143 
The aim is to understand the frequency of 143 in 2645997.

Let's proceed to step 1:
The number 143 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 143

On to step 2:
26 divided by 143 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 143

Let's proceed to step 3:
143 can be fit into 264 1 times, resulting in a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 121 after subtracting 143 from 264.
Append the next digit (5) from the dividend to 121 and continue with: 1215 / 143

On to step 4:
The number 143 fits into 1215 8 times, leaving a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 1144 from 1215, we get 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 143

Let's proceed to step 5:
719 divided by 143 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 185.0
The remainder is 4 after subtracting 715 from 719.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 143

Going ahead to step 6:
The number 143 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1850.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 143

Going ahead to step 7:
143 goes into 497 3 times with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 18503.0
If we take 429 away from 497, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
680 divided by 143 is 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 18503.4
Subtracting 572 from 680 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 9:
1080 divided by 143 is 7 with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 18503.47
If we subtract 1001 from 1080, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
If we divide 790 by 143, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 18503.475
Subtract 715 from 790 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
The number 143 fits into 750 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 18503.4755
If we take 715 away from 750, we end up 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.

In conclusion, the division gives 18503.4755 with a balance of 0.00035.
