We're dividing 253916 by 86 
Our goal is to divide 253916 by 86.

Advancing to step 1:
2 divided by 86 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 86

Moving on to step 2:
25 divided by 86 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 86

Step 3:
86 can be fit into 253 2 times, resulting in a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 172 from 253 and we're left with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 86

Going ahead to step 4:
When dividing 819 by 86, we get 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 774 from 819 to get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 86

Advancing to step 5:
86 can be fit into 451 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 295.0
Deduct 430 from 451 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 86

Let's proceed to step 6:
The number 86 fits into 216 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2952.0
Subtract 172 from 216 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
86 goes into 440 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2952.5
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 2952.51
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 86, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 2952.511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 2952.511 with a remainder of 0.0054.
