We look at the division of 842126 by 3 
Our goal is to divide 842126 by 3.

Moving on to step 1:
8 divided by 3 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Going ahead to step 2:
If we divide 24 by 3, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Step 3:
If we divide 2 by 3, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 280.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Moving on to step 4:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 2807.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

On to step 5:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 28070.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Moving on to step 6:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 280708.0
Deduct 24 from 26 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 280708.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 280708.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 280708.66, and the remainder is 0.002.
