We look at the division of 399525 by 3 
Our goal is to divide 399525 by 3.

On to step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Advancing to step 2:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Let's proceed to step 3:
If we divide 9 by 3, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 9 away from 9, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

On to step 4:
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: 1331.0
If we take 3 away from 5, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 5:
If we divide 22 by 3, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 13317.0
Subtract 21 from 22 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Moving on to step 6:
3 goes into 15 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 133175.0
If we take 15 away from 15, 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.

Going ahead to step 7:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 133175.0
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.

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 133175.0
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 133175.0 with a balance of 0.0.
