We're dividing 503757 by 3 
We want to figure out the number of times 503757 can be divided by 3.

Advancing to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Let's proceed to step 2:
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: 16.0
The remainder is 2 after subtracting 18 from 20.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Let's proceed to step 3:
When dividing 23 by 3, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Step 4:
When dividing 27 by 3, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1679.0
Subtract 27 from 27 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Going ahead to step 5:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 16791.0
Subtract 3 from 5 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Going ahead to step 6:
If we divide 27 by 3, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 167919.0
Deduct 27 from 27 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.

Going ahead to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 167919.0
The remainder is 0 after subtracting 0 from 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:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 167919.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 167919.0 with a balance of 0.0.
