We look at the division of 374500 by 3 
We're looking to find how many times 3 goes into 374500.

Step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

On to step 2:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

On to step 3:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Advancing to step 4:
3 goes into 25 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 1248.0
Subtract 24 from 25 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Let's proceed to step 5:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 12483.0
Subtract 9 from 10 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Moving on to step 6:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 124833.0
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.

Advancing to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 124833.3
Deduct 9 from 10 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.

Moving on 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: 124833.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 124833.33 with a balance of 0.001.
