891664 ÷ 3 
Our goal is to divide 891664 by 3.

Step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 2:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 27 from 29 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Moving on to step 3:
3 goes into 21 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 297.0
If we take 21 away from 21, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Going ahead to step 4:
6 divided by 3 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2972.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Going ahead to step 5:
3 can be fit into 6 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 29722.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Going ahead to step 6:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 297221.0
Subtracting 3 from 4 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 297221.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 297221.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 297221.33 with a remainder of 0.001.
