We divide 514815 by 3
We're looking to find how many times 3 goes into 514815.

On to step 1:
If we divide 5 by 3, we get 1 and 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 2:
3 goes into 21 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 21 from 21 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Moving on to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtracting 3 from 4 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to step 4:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1716.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

On to step 5:
When dividing 1 by 3, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 17160.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Let's proceed to step 6:
3 goes into 15 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 171605.0
Subtract 15 from 15 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.

Let's proceed to step 7:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 171605.0
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.

Let's proceed to step 8:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 171605.0
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.

The final outcome is 171605.0, with a leftover of 0.0.
