We're dividing 817634 by 3 
We want to divide 817634 by 3.

Going ahead to step 1:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Advancing to step 2:
3 goes into 21 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 21 from 21 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Let's proceed to step 3:
If we divide 7 by 3, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 272.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Moving on to step 4:
16 divided by 3 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 2725.0
If we take 15 away from 16, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

On to step 5:
When dividing 13 by 3, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 27254.0
If we subtract 12 from 13, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Moving on to step 6:
The number 3 fits into 14 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 272544.0
If we take 12 away from 14, 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.

Going ahead to step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 272544.6
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:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 272544.66
If we subtract 18 from 20, we 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 final outcome is 272544.66, with a leftover of 0.002.
