We divide 458938 by 3
We're looking to find how many times 3 goes into 458938.

Advancing to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 2:
3 goes into 15 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 15 from 15 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Advancing to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 152.0
If we subtract 6 from 8, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Going ahead to step 4:
3 can be fit into 29 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1529.0
If we take 27 away from 29, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Moving on to step 5:
When dividing 23 by 3, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 15297.0
If we take 21 away from 23, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

On to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 152979.0
Deduct 27 from 28 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 152979.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 152979.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 152979.33 with a remaining 0.001.
