We're dividing 853257 by 3 
We want to figure out the number of times 853257 can be divided by 3.

Going ahead to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

On to step 2:
25 divided by 3 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 24 from 25 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Step 3:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 284.0
Subtract 12 from 13 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Advancing to step 4:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 2844.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Going ahead to step 5:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 28441.0
If we take 3 away from 5, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Advancing to step 6:
3 goes into 27 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 284419.0
Subtract 27 from 27 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 284419.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 284419.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 284419.0 and a remainder of 0.0.
