We look at the division of 862174 by 3 
We want to divide 862174 by 3.

On to step 1:
3 goes into 8 2 times with 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.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Advancing to step 2:
26 divided by 3 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 24 from 26, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Let's proceed to step 3:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 287.0
If we subtract 21 from 22, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Let's proceed to step 4:
The number 3 fits into 11 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 2873.0
The remainder is 2 after subtracting 9 from 11.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Moving on to step 5:
3 goes into 27 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 28739.0
If we take 27 away from 27, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Moving on to step 6:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 287391.0
If we take 3 away from 4, 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.

Going ahead to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 287391.3
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.

Advancing to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 287391.33
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 quotient of the division is 287391.33, and the remainder is 0.001.
