We divide 803791 by 3
We're looking to find how many times 3 goes into 803791.

Advancing to step 1:
8 divided by 3 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 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.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 18 from 20 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Advancing to step 3:
When dividing 23 by 3, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
The remainder is 2 after subtracting 21 from 23.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Moving on to step 4:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2679.0
The remainder is 0 after subtracting 27 from 27.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

On to step 5:
3 goes into 9 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 26793.0
Subtract 9 from 9 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

On to step 6:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 267930.0
The remainder is 1 after subtracting 0 from 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.
The number 3 becomes the next digit in our result. 
Result so far: 267930.3
Subtract 9 from 10 to 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.

Going ahead to step 8:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 267930.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 267930.33, and the remainder is 0.001.
