We're dividing 978581 by 3 
Let's see how many times 3 fits into 978581.

Moving on to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Advancing to step 2:
When dividing 7 by 3, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Advancing to step 3:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 326.0
If we take 18 away from 18, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

On to step 4:
5 divided by 3 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 3261.0
Deduct 3 from 5 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Advancing to step 5:
If we divide 28 by 3, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 32619.0
Subtracting 27 from 28 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 326193.0
The remainder is 2 after subtracting 9 from 11.
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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 326193.6
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.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 326193.66
The remainder is 2 after subtracting 18 from 20.
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 326193.66 and a remainder of 0.002.
