Let's divide 142990 by 6
Our goal is to divide 142990 by 6.

Going ahead to step 1:
1 divided by 6 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 6

Step 2:
6 can be fit into 14 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 12 from 14 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 6

Let's proceed to step 3:
6 can be fit into 22 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 4 after subtracting 18 from 22.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 6

Advancing to step 4:
When dividing 49 by 6, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 238.0
Subtracting 48 from 49 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 6

Moving on to step 5:
19 divided by 6 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2383.0
Deduct 18 from 19 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 6

Moving on to step 6:
6 goes into 10 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 23831.0
The remainder is 4 after subtracting 6 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 6, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 23831.6
Subtracting 36 from 40 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:
40 divided by 6 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 23831.66
Deduct 36 from 40 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.

The final result is 23831.66 with a remainder of 0.004.
