Let's divide 253384 by 3
We're looking to find how many times 3 goes into 253384.

On to step 1:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Let's proceed 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: 8.0
If we subtract 24 from 25, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Step 3:
13 divided by 3 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 84.0
If we take 12 away from 13, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Step 4:
13 divided by 3 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 844.0
Subtract 12 from 13 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 5:
When dividing 18 by 3, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 8446.0
If we take 18 away from 18, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Let's proceed to step 6:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 84461.0
Deduct 3 from 4 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 84461.3
The remainder is 1 after subtracting 9 from 10.
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 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 84461.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 84461.33 and a remainder of 0.001.
