We're dividing 550959 by 3 
We want to divide 550959 by 3.

Moving on to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Advancing to step 2:
25 divided by 3 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 24 from 25, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Step 3:
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: 183.0
Subtract 9 from 10 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Moving on to step 4:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 1836.0
If we take 18 away from 19, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

On to step 5:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 18365.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Advancing to step 6:
3 goes into 9 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 183653.0
If we subtract 9 from 9, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 183653.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 183653.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 183653.0, and the remainder is 0.0.
