We're dividing 743950 by 3 
We're looking to find how many times 3 goes into 743950.

Going ahead to step 1:
3 goes into 7 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Let's proceed to step 2:
If we divide 14 by 3, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 2 after subtracting 12 from 14.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Step 3:
If we divide 23 by 3, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 247.0
If we subtract 21 from 23, 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 goes into 29 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 2479.0
Subtract 27 from 29 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

On to step 5:
If we divide 25 by 3, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 24798.0
Subtract 24 from 25 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Let's proceed to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 247983.0
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.

On to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 247983.3
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.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 247983.33
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.

The quotient of the division is 247983.33, and the remainder is 0.001.
