522451 ÷ 3 
Our goal is to divide 522451 by 3.

Step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 2:
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: 17.0
The remainder is 1 after subtracting 21 from 22.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Let's proceed to step 3:
3 goes into 12 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 174.0
Subtract 12 from 12 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Step 4:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1741.0
Subtracting 3 from 4 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Going ahead to step 5:
3 goes into 15 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17415.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

Moving on to step 6:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 174150.0
If we subtract 0 from 1, we 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.

Moving on to step 7:
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: 174150.3
If we subtract 9 from 10, we 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.

Step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 174150.33
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 174150.33 with a balance of 0.001.
