We look at the division of 28123960 by 143 
Let's see how many times 143 fits into 28123960.

Step 1:
2 divided by 143 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 143

Step 2:
When dividing 28 by 143, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 143

Advancing to step 3:
143 goes into 281 1 times with a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 143 from 281, we get 138.
Bring next digit (2) of the dividend behind the 138 and repeat the process: 1382 / 143

Going ahead to step 4:
If we divide 1382 by 143, we get 9 and a remainder of 95.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 95 after subtracting 1287 from 1382.
Fetch the next digit (3) from the dividend, attach it to 95 and continue: 953 / 143

On to step 5:
The number 143 fits into 953 6 times, leaving a remainder of 95.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtract 858 from 953 to get 95.
Fetch the next digit (9) from the dividend, attach it to 95 and continue: 959 / 143

On to step 6:
959 divided by 143 is 6 with a remainder of 101.
The next digit of our result is 6. 
Result so far: 1966.0
Subtracting 858 from 959 leaves us with 101.
Bring next digit (6) of the dividend behind the 101 and repeat the process: 1016 / 143

Let's proceed to step 7:
When dividing 1016 by 143, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 19667.0
If we subtract 1001 from 1016, we get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 143

Moving on to step 8:
If we divide 150 by 143, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 196671.0
Subtract 143 from 150 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 143 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 196671.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
700 divided by 143 is 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 196671.04
If we subtract 572 from 700, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
143 goes into 1280 8 times with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 196671.048
Deduct 1144 from 1280 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
The number 143 fits into 1360 9 times, leaving a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 196671.0489
Subtract 1287 from 1360 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 13:
143 can be fit into 730 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 196671.04895
Deduct 715 from 730 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
When dividing 150 by 143, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 196671.048951
Subtract 143 from 150 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 15:
70 divided by 143 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 196671.048951
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
If we divide 700 by 143, we get 4 and a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 196671.04895104
Deduct 572 from 700 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Our division results in 196671.04895104 with a remaining 1.28e-07.
