Let's divide 155615 by 3
Let's see how many times 3 fits into 155615.

Advancing to step 1:
3 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Let's proceed to step 2:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 15 from 15 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

On to step 3:
5 divided by 3 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 3 from 5, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

On to step 4:
26 divided by 3 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Let's proceed to step 5:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 5187.0
The remainder is 0 after subtracting 21 from 21.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Advancing to step 6:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 51871.0
Subtract 3 from 5 to 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.

Advancing to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 51871.6
Deduct 18 from 20 and we're left 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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 51871.66
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.

The final outcome is 51871.66, with a leftover of 0.002.
