253003 divided by 86 
We want to divide 253003 by 86.

Going ahead to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 86

Step 2:
86 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 86

Moving on to step 3:
If we divide 253 by 86, we get 2 and a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 172 away from 253, we end up with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 86

On to step 4:
810 divided by 86 is 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 774 from 810 to get 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 86

Going ahead to step 5:
86 goes into 360 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Subtract 344 from 360 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 86

Moving on to step 6:
86 can be fit into 163 1 times, resulting in a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 2941.0
Deduct 86 from 163 and we're left with 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:
When dividing 770 by 86, we get 8 with a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 2941.8
The remainder is 82 after subtracting 688 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
820 divided by 86 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 2941.89
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
86 can be fit into 460 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2941.895
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.

Step 10:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 2941.8953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
When dividing 420 by 86, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 2941.89534
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.

Advancing to step 12:
86 goes into 760 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 2941.895348
Deduct 688 from 760 and we're left with 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.
Put 8 as the next digit of the answer. 
Result so far: 2941.8953488
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.

After the division, we end up with 2941.8953488 and a remainder of 3.2e-07.
