We look at the division of 86284949 by 253 
We want to figure out the number of times 86284949 can be divided by 253.

Moving on to step 1:
When dividing 8 by 253, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 253

On to step 2:
The number 253 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 253

Going ahead to step 3:
862 divided by 253 is 3 with a remainder of 103.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 759 from 862, we get 103.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 253

Moving on to step 4:
1038 divided by 253 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 1012 from 1038 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 253

Step 5:
264 divided by 253 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 341.0
Deduct 253 from 264 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 253

Moving on to step 6:
253 goes into 119 0 times with a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 3410.0
If we take 0 away from 119, we end up with 119.
Bring next digit (4) of the dividend behind the 119 and repeat the process: 1194 / 253

Moving on to step 7:
253 goes into 1194 4 times with a remainder of 182.
The next digit of our result is 4. 
Result so far: 34104.0
Subtracting 1012 from 1194 leaves us with 182.
Fetch the next digit (9) from the dividend, attach it to 182 and continue: 1829 / 253

Advancing to step 8:
When dividing 1829 by 253, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 341047.0
The remainder is 58 after subtracting 1771 from 1829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
The number 253 fits into 580 2 times, leaving a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 341047.2
The remainder is 74 after subtracting 506 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
If we divide 740 by 253, we get 2 and a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 341047.22
If we subtract 506 from 740, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final result is 341047.22 with a remainder of 0.234.
