742521 ÷ 3 
Let's see how many times 3 fits into 742521.

Let's proceed to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Going ahead to step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 24.0
If we take 12 away from 14, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Going ahead to step 3:
If we divide 22 by 3, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 247.0
If we take 21 away from 22, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

On to step 4:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2475.0
Subtracting 15 from 15 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

On to step 5:
If we divide 2 by 3, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 24750.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Going ahead to step 6:
21 divided by 3 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 247507.0
Subtracting 21 from 21 leaves us 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.

Advancing to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 247507.0
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:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 247507.0
Subtracting 0 from 0 leaves us 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.

The final result is 247507.0 with a remainder of 0.0.
