We divide 302846 by 3
We want to figure out the number of times 302846 can be divided by 3.

Going ahead to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 2:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

On to step 3:
2 divided by 3 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

On to step 4:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
If we subtract 27 from 28, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

On to step 5:
If we divide 14 by 3, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 10094.0
Subtract 12 from 14 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Going ahead to step 6:
When dividing 26 by 3, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 100948.0
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.

Advancing to step 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 100948.6
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: 100948.66
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.

After the division, we end up with 100948.66 and a remainder of 0.002.
