We divide 90644 by 3
We want to figure out the number of times 90644 can be divided by 3.

Moving on to step 1:
9 divided by 3 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Let's proceed to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Moving on to step 3:
3 goes into 6 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 302.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Step 4:
When dividing 4 by 3, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3021.0
If we subtract 3 from 4, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Moving on to step 5:
14 divided by 3 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 30214.0
Subtracting 12 from 14 leaves us 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.

Going ahead to step 6:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 30214.6
Deduct 18 from 20 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.

Moving on to step 7:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 30214.66
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 30214.66, and the remainder is 0.002.
