We're dividing 146531 by 3 
We're looking to find how many times 3 goes into 146531.

On to step 1:
1 divided by 3 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Moving on to step 2:
3 goes into 14 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 12 from 14 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Let's proceed to step 3:
3 goes into 26 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 24 from 26 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Advancing to step 4:
3 goes into 25 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.0
If we take 24 away from 25, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Advancing to step 5:
If we divide 13 by 3, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4884.0
If we take 12 away from 13, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Let's proceed to step 6:
If we divide 11 by 3, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 48843.0
Deduct 9 from 11 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.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 48843.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 48843.66
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.

In conclusion, the division gives 48843.66 with a balance of 0.002.
