We look at the division of 143198 by 28 
We're looking to find how many times 28 goes into 143198.

Step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 28

On to step 2:
28 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 28

Moving on to step 3:
28 can be fit into 143 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 140 from 143 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 28

Step 4:
28 goes into 31 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 3 after subtracting 28 from 31.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 28

Step 5:
39 divided by 28 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 511.0
If we take 28 away from 39, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 28

Step 6:
28 goes into 118 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 5114.0
Subtract 112 from 118 to 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.

Let's proceed to step 7:
If we divide 60 by 28, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 5114.2
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 5114.21
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5114.214
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 5114.2142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 5114.21428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5114.214285
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 5114.2142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 5114.21428571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5114.21428571 with a remainder of 1.2e-08.
