We look at the division of 93499883 by 143 
The aim is to understand the frequency of 143 in 93499883.

Going ahead to step 1:
9 divided by 143 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 143

Advancing to step 2:
143 can be fit into 93 0 times, resulting in a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Grab the next digit (4) from the dividend, add it to 93, then carry on: 934 / 143

Step 3:
934 divided by 143 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 858 from 934, we get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 143

Going ahead to step 4:
769 divided by 143 is 5 with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 54 after subtracting 715 from 769.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 143

Let's proceed to step 5:
143 goes into 549 3 times with a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 653.0
Subtract 429 from 549 to get 120.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 143

Let's proceed to step 6:
143 goes into 1208 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 6538.0
If we subtract 1144 from 1208, we get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 143

Going ahead to step 7:
648 divided by 143 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 65384.0
Subtract 572 from 648 to get 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 143

Going ahead to step 8:
If we divide 763 by 143, we get 5 and a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 653845.0
Subtract 715 from 763 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
480 divided by 143 is 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 653845.3
If we take 429 away from 480, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
510 divided by 143 is 3 with a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 653845.33
The remainder is 81 after subtracting 429 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 653845.33, with a leftover of 0.081.
