We look at the division of 525248 by 3 
We're looking to find how many times 3 goes into 525248.

Advancing to step 1:
5 divided by 3 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Moving on to step 2:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 21 away from 22, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

On to step 3:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 175.0
Deduct 15 from 15 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Moving on to step 4:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1750.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Going ahead to step 5:
When dividing 24 by 3, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 17508.0
Subtracting 24 from 24 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Let's proceed to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 175082.0
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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 175082.6
If we subtract 18 from 20, we get 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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 175082.66
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.

The quotient of the division is 175082.66, and the remainder is 0.002.
