Let's divide 253949 by 86
Let's see how many times 86 fits into 253949.

On to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 86

Step 2:
86 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 86

Step 3:
253 divided by 86 is 2 with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 172 from 253 and we're left with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 86

Step 4:
86 goes into 819 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 45 after subtracting 774 from 819.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 86

Let's proceed to step 5:
If we divide 454 by 86, we get 5 and a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
Subtract 430 from 454 to get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 86

Let's proceed to step 6:
When dividing 249 by 86, we get 2 with a remainder of 77.
The next digit of our result is 2. 
Result so far: 2952.0
Subtract 172 from 249 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
86 can be fit into 770 8 times, resulting in a remainder of 82.
The next digit of our result is 8. 
Result so far: 2952.8
If we subtract 688 from 770, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 8:
When dividing 820 by 86, we get 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 2952.89
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
If we divide 460 by 86, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2952.895
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 86, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 2952.8953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 2952.89534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
760 divided by 86 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 2952.895348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 2952.8953488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 2952.8953488 with a balance of 3.2e-07.
