We're dividing 801484 by 3 
We're looking to find how many times 3 goes into 801484.

Advancing to step 1:
8 divided by 3 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Going ahead to step 2:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 18 from 20 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Step 3:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 267.0
The remainder is 0 after subtracting 21 from 21.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Moving on to step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 2671.0
Subtract 3 from 4 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

On to step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 26716.0
Subtracting 18 from 18 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Moving on to step 6:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 267161.0
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.

On 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: 267161.3
If we subtract 9 from 10, we get 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:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 267161.33
Deduct 9 from 10 and we're left 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.

Our division results in 267161.33 with a remaining 0.001.
