We're dividing 48180623 by 3 
Our goal is to divide 48180623 by 3.

On to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Let's proceed to step 2:
3 goes into 18 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
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

Let's proceed to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 160.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

On to step 4:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 1606.0
Deduct 18 from 18 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 5:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16060.0
If we subtract 0 from 0, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Moving on to step 6:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 160602.0
If we subtract 6 from 6, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

On to step 7:
3 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1606020.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Moving on to step 8:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 16060207.0
Subtract 21 from 23 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 9:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16060207.6
If we subtract 18 from 20, we 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.

Going ahead to step 10:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16060207.66
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 16060207.66, with a leftover of 0.002.
