143189 ÷ 27 
Our goal is to divide 143189 by 27.

Step 1:
27 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 27

Moving on to step 2:
14 divided by 27 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 27

Moving on to step 3:
If we divide 143 by 27, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 135 from 143 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 27

Going ahead to step 4:
27 can be fit into 81 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 0 after subtracting 81 from 81.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 27

Step 5:
When dividing 8 by 27, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 530.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 27

On to step 6:
89 divided by 27 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 5303.0
If we take 81 away from 89, we end up 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.

Step 7:
80 divided by 27 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 5303.2
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
When dividing 260 by 27, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 5303.29
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
When dividing 170 by 27, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 5303.296
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
27 goes into 80 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 5303.2962
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
If we divide 260 by 27, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 5303.29629
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
27 can be fit into 170 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 5303.296296
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 27 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 5303.2962962
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 27, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 5303.29629629
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 5303.29629629, with a leftover of 1.7e-08.
