525278 ÷ 3 
We want to figure out the number of times 525278 can be divided by 3.

Advancing to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Step 2:
The number 3 fits into 22 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 21 from 22 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 3:
If we divide 15 by 3, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Subtracting 15 from 15 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Going ahead to step 4:
When dividing 2 by 3, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1750.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Step 5:
When dividing 27 by 3, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 17509.0
The remainder is 0 after subtracting 27 from 27.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 175092.0
The remainder is 2 after subtracting 6 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 175092.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 175092.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 175092.66 and a remainder of 0.002.
